We are drip feeding from a calmotion usb to our fadal and get an alarm - N word exceeds 99,999. Is there anyway around this? I am thinking about editing the post to increment line numbers by .1 instead of 1 (ex. N1.1 N1.2 N1.3 etc.) is this possible? Any other suggestions or recommendations? This machine has a -4 processor if that makes a difference. Breaking down programs and babysitting is a huge PITA. We typically program in Fusion360 but also have Mastercam available. I find it hard to believe the machine cant handle more than 99,999 lines especially when drip feeding but then again, its a fadal...:angry:

Narrow slot roughing tactics
I need to create a .375" deep, .125"( +.01, - 00) slot in 304ss. It's a 16.5" diameter circle in the face of a tube sheet for seating filter elements. Unfortunately I can't turn the part, lathe is a smidge too small so it's going on the VMC.
Would you guys HEM this with an undersized tool, run it traditionally with an 1/8" rougher, or something else?
The job was priced with a traditional slow movin path in mind so if that's the best way Im covered but I feel like there's a more efficient method.
Thanks, Cole

Spindle Drive Repair On A Citizen Swiss
I have a 1990 Citizen L10 Swiss CNC and the spindle drive (actually inverter) is acting up. Spindle will be rolling along just swell and then blast off to full speed out of no where and will stay stuck there.
The machine controls are Yaskawa but the spindle control is Mitsubishi - P/N FR-Z220-3.7K
I called Mitsubishi and they won't touch it. Looking for some known repair shops that can handle this.
Hoping to get some references from you all.
Thanks much.

Drilling 20mm in mild steel tips
Hi guys,
Have a Hurco VM10 (quite a small mill) and need to drill 20mm x 40 deep into 140 off Mild Steel billets.
Would you guys use a series of drills working up to 20mm or just spot and then straight to it?
Its a good quality HSS bit but have no through coolant on machine.
Thanks in advance.

Indramat KDA 3.2-100-3-A00-W1 - any way to troubleshoot (spindle won't spin up)
Got this Indramat KDA 3.2-100-3-A00-W1 on a TOS cnc machine with a Heidenhain 407, I can't get the spindle to spin up, and I'm kinda thinking it might be something wrong with the spindle drive - even though it says "ready", and it looks like it get different parameters etc, but it showd N * NCMD.
The 407 have a "star" coming on so it thinks it's running the spindle given the M03 command - but I get no power out of the spindle drive.
Is there any feedbacks the spindle drive need to output any power, or is it something else that might "stop" it.
If I disconnect some of the plugs it reports things like "No Power", "NO RF" etc, so it seem to be "sensing".....
Any tips on checks one can do would be appreciated.
Also - does anyone know if the X12 connector the T2 should be shorted to ground ? (on the drive itself as it shorts when cables are disconnected - it's the connector for the Thermistor).

Vturn 26 OI-TB spindle alarm 15
Hi guys
Would anyone out there have a pdf copy of the wiring schematics for a Vturn 26 using a Fanuc OI-TB control. I have inherited a problem with no schematics and I am trying to chase down a spindle amplifier alarm 15.Contactors are all good, need to start hunting down bad wiring I think. Any help would certainly be appreciated.

Haas Deflection/out of tolerance
Hi I have a 1999 Haas VF0 that I'm fighting deflection.
Have to make multiple repeat passes to get close to my feature dimensions.
I have installed: all new ball screws in all axis, Z axis linear rails and a new spindle all within the last 6 months.
For example - 1/2 niagra 3 flute 2" loc in Haimer shrink fit .0002" runout
Cutting Aluminum
7500 rpm.
1.5" doc
.020" radial
50ipm
I have 2000 lbs drawbar pressure.
getting .007" off of programmed feature at the top and .013" at the bottom both X and Y are the same.
after running 2 more (spring passes) i was .001" over on top and .0025" on bottom.
Because of the taper it makes most sense that the problem is in Z.
Open to any suggestions.

Expanding Haas Tool Offset Table - Haas VF-5
I know how to expand the offset table to include 200 tool height offsets but I am wondering if there is a way to get more. I know I can have tool height offsets stored in macro variables but I would rather not go that route. Has anyone else found a solution for this? Can a haas service rep upgrade the the control to accommodate this request?

Need help: ATC carousel bounces on '93 Leadwell MCV-0P w fanuc Series 0
Hi
We have a '93 leadwell MCV-0P w fanuc Series 0 that looks like a weird ATC bouncing problem during M06 operation. M23/M24 operations do not bounce.
I say "looks like" because we don't know if this is normal for this machine. We don't know much about this machine, we don't have manuals except for a parameter manual for a similar machine.
During M06 extracting a tool, the carousel grabs the tool, moves down 1/8 inch bounces back up, then fully drops to extract the tool. When inserting a tool, the tool inserts, then it bounces down about an inch and returns to the change position.
The problem is the pocket's holding clips smash into the tool holder in the spindle.
I'm fairly sure bouncing is not correct.
Here's links to videos showing the insert bounce. One video shows the carousel, the other shows the micro switches

TNCremo/Server and Heidenhain TNC 407
Been trying to make a backup of the tnc, and have been trying to transfer files via the tncserver program.
I was able to get it to output a .h file to the server, but it only displayed it's content in the "status window" of the server. when trying to copy files to the computer it seem to start (it creates the file on the pc), but then it stalls, the tnx seem to be working on transfer but nothing really happens, and I end up with a 0kb file (empty)).
I presume this might have to do with some wrong settings - can anyone confirm the settings of the COM port on the computer that have worked for them with the 407 ?.
Or have experienced this problem before and are able to give some pointers ?.

Matsuura MC-450H-30-PC11
So I impulse bought an old school Matsuura (1991) at auction a week ago.
The thing has 100 tools and 11 pallets.
It's been years since I worked on the Yasnac MX3 control, but I have never worked on one with a multi pallet pool system.
So.. I tore it down myself at auction, had the riggers transport and installed myself.
We got all the parts back together and operational without any problems.
Now.. the application....
It has a pallet scheduler, where you schedule the pallets by an assigned program. Similar to the Haas schedulers... but we don't use those on our Haas.
My question....
Is there a program level strategy that one can use to change programs? On our Haas we can do an M50 P1(P2) to designate which pallet to change for programming purposes.
As far as I can tell reading all the books that came with it.. I am not finding something like that with this old school pallet changer.
The scheduler can find and change pallets... we should be able to do it with programming.
If, I manually change a pallet with the over ride switches, the control will not update the pallet in the machine.. which leads me to believe it's controlled by the scheduler and similar to the random pocket tool change cycle.
Anyone have any information were the pallet order is stored in these controls either by variable or parameter?
If I can figure that out I should be able to program it by macros.
Any info would be great!
Thanks,
Mike in MN

Rotary table chuck thoughts?
I'm looking for a 6 inch chuck for my smaller rotary. The rotary is one of the Haas HRC-160 units.
What are your thoughts on 3 jaw vs 6 jaw chucks for general rotary work? I'm kind of leaning toward 6 jaw right now. I've been kicking around going with a 16c collet chuck also but I think that may be a different tool all together.

GSK controller Query
Good day all,
Has anybody had experience on a GSK928TD-L controller, specifically around the CREATING OF A CORDINATING SYSTEM? I bought the controller as I was informed that it is similar to the FANUC controllers which I have many years of experience. Fanuc is similar to the GSK980 controller, but the GSK 928 is totally different from what I am seeing.
Is the Machine Reference or Machine Zero return required? The supplier tells me it is not and that it functions on floating system but did not explain further, the manual is barely legible and I am unsure how to proceed. For clarity:
What is the machine zero position and how is it found/set?
What is the program zero position and how is it set?
What is the job Z 0.0 position and how does it differ to the program zero position?
The problem I have is that the program starts running from where it came to an end and does not return to the absolute X and Z (the edge of the part been turned) of the program. The error grows progressively with each component machined.
Any assistance or examples would be greatly appreciated.

Is UMC-750 that bad?
I can get a slightly used 2019 model UMC-750 for a really good price and I don't know any one who owns one so I searched the web on UMC's and I am a bit puzzled

UMC-750 Applications Troubleshooting Guide
When Drilling From B90 C0 to B90 C180 The Holes Don't Line Up:
On a UMC-750, when using a drill from two sides of a part you can get up to 0.002 inch (0.051 mm) error per side.
This can add up to a total of 0.004 inch (0.102 mm) mismatch between the two drilled holes.
Use a probe to get separate offsets for the B90 C0 and B90 C180 side. This can reduce this mismatch error.
^ Are these "Accuracy Errors" and "Surface Finish Problems" worst case scenarios or common numbers for UMC-750? Since Haas tweaks-improves their machines, is there a change that 2019 model UMC-750 might be better?
Or are these error are caused by low resolution rotary scales and lack of scales on linear axes??
Strategies for solving UMC surface finish problems
Make sure the tooling is correct for the application. Gage length should be as short as possible. Use milling chucks or shrink-fit holders. If that's not possible use ER collets. Avoid Weldon shank holders. Endmill runout needs to be under 0.0005â€. Balance all tools that turn 10,000rpm or more to grade G2.5 or better
Can I really improve accuracy, finish quality by tweaking the code and using milling chucks or shrink-fit holders and tweaking the code?
Further more they redesigned their rotaries with Cycloidal Rotary Drives on UMC-500 and UMC-1000 and I guess they are going to refresh UMC-750 soon.
UMC-750's cutting and rapid speeds are really far apart compared to other Haas machines [1200ipm vs 650ipm] UMC-750 moves like SS [1400ipm] and cuts as fast as regular VF [650 ipm].
Weirdly, UMC-750 and UMC-750SS's Feedrates are identically same on the Haas's website, I guess they might did an error on the website.
Any comment will be vastly appreciated.
My other alternative is a equivalently used and specd 3+2 DMG MORI CMX 50 U which costs %20 more, offer bigger table but smaller work envelop and comes with linear scales.

fryer IO card CAN bus problems
Hey folks.
Im new to cnc, although Ive been 3D printing for 7 years now. I built my 3D printer and 150 more.
I recently bought a fryer mini mill. Really nice machine. Flat screen (not 80 tech), win 386, 10 position tool changer, coolant, enclosed etc. The whole shebang. Took me a whole year to get a phase converter, set it up, plumb air lines in my workshop, and get the thing started up. I replaced air lines, push to connect fitting, because it was leaking everywhere. Some of the features did not work, like the tool magazine motor, the boost cylinder etc. While poking around in the cabinet I found that some of the wire connectors are loose. Once I connected it back everything worked as it should.
Wanted to prevent it happening again. Fryer used multiple IO cards with CAN bus connection to hook up enough IO cards. There is a female header surface mounted on the pcb. Then they insert a male-male connector, then plug in the cable with wires. The thing is a rat-trap. I designed and 3D printed connectors, took a bunch of pictures, drew schematics, marked mating parts, disassembled it and assembled the brackets, put everything together, and now its not working again. Wanted to make it more bullet proof and screwed it up. All the peripherals that does not work seem to be on the same IO card. Found out that the IO cards have 2 areas with jumpers. Some of the jumpers are populated, some of them are just parked.
Computer starts normally. There are no error messages of any kind when the machine starts up or when its running. If I press the tool-cw, tool-ccw, light or tool release buttons, any of the end switches on the boost cylinder or on the tool changer cylinder the leds will come on on the IO boards input side. Some of the IO boards will flash the output LEDs too.
Ive got the 3D models for the brackets if someone wants to use them (tear up their cnc 😊 )
Any advice is appreciated on how to troubleshoot this. Thank you.

Ive got the 3D models for the brackets if someone wants to use them (tear up their cnc 😊 )
Any advice is appreciated on how to troubleshoot this. Thank you.
