Mach4 General Discussion / Re: Finial switching over to Mach4 amd Ihave a few question.

Not sure I understand!  My X axis is motor 0, my Y axis is motor 1 & motor 3 (slave) and my A axis is the rotary axis - motor 4. When using the rotary CNC setup the Vcarve file sends the "Y" axis code to the "A" axis, as the "Y" axis stays at 0.000. My setting for the "A" axis is 26.7 counts per degree @ velocity of 4994 which rotates 1 rev for 360º. ( A axis is a belt driven 1:6 ratio)

Here is the settings that work with CNC set for MM. If I setup for INCH & change X, Y, & Z and leave A alone the A axis now turns too slow when I use the same Gcode files.

ESS CNC Rotary
The opposite happens - the linear axis (Y) 7 (Z) are OK its the wrapping of (X) which slows down. With th machine setup in MM all file works OK for both MM & Inch files. If I set the machine up for INCHES the inch files no longer feeds fast enough in the rotary axis. When I change motor 4 tuning I lose 360º per rev.

Thanks Craig,

Now I have a rotary axis question for mach 4. I created some G code  in V carve to test the rotary axis.  My feed rate for my tool was 60 inch/min in v carve.  Mach 4 thinks it is 60 degree/min, to slow.

In mach 3 there was setting where you could tell mach it was a rotary job and it would compensate or adjust the speed.  Can I set that up in Mach 4?   Did I miss something in my setup?
I could make rotary tool in V carve software and crank the speed way up.
Thanks,
Todd

I have the same problem! If i set my CNC up as all METRIC when I use an INCH G-code file everything works great for rotary engraving feed speeds. If I set up my CNC for INCH & re-tune motors rotary speed is too slow! MACH4 with ESS Smoothstepper using VCarve files. Something is wrong in the MACH4 calculations for INCH to degrees! I've not got any answers on this problem that works - I would like to keep my Inch machine setup for 4th axis!

Check your analog input voltage to your VFD and the on/off input to VFD. My setup only has 2 wires for the  turning on/off going to terminal DCM & FOR and 2 wires for the analog  (0 -10vdc) going to terminals ACM & V1 on my Huanyang Inverter. Also make sure your VFD (inverter) settings are correct for your spindle motor.

In addition to the information I supplied in my post, I had to set the UC100 Spindle setup to pin 1 and check the negative box.

Subject: Setup Spindle for PWM
 
 
Thank you for replying! I Think I finally got the UC100 setup right! I now have Output Signals set as follows: Output #1 UC100 Port1 Pin1, Spindle On UC100 Port1 Pin17, Spindle Fwd Port1 Pin14. Spindle 0 MinRPM 0.00, MaxRPM 24000. The only thing I need to do now is see if there is a way to display current RPM & calibrate a scale. If you have any pointers, I would appreciate any suggestions!

I think my problem was screwing around in the UC100 plugin. I contacted them and they said:

Hi,

I have checked the problem and the Spindle Mode dropdown box is obselete and it seems that my collegues accidentally forgot to remove it from the plugin form.
So, the Spindle Mode dropbox on the plugin form does nothing now and is already removed from the form in the upcoming plugin release.
If you want step/dir spindle then in the Mach configuration on the Spindle tab page there is a "Step/dir spindle Axis" selection and select the axis in that dropdown or select none if you want PWM spindle.

Best Regards,
Balazs

I have the same problem with UC100! Worked fine with Mach3. I can turn on my spindle but can't get PWM to work.  Any help yet?
