I am looking for guidance on how to setup the C axis as a second spindle.  This is for a rose engine lathe (otbok.info/index.php?n=Main.RoseEngineLathe) where we need to use:

1. the Spindle to rotate the piece, and
2. the C axis to rotate the rosettes used to impart the design

We turn these quite slowly, certainly less than 10 RPM, and at times speeds approaching 3 or 4 minutes per revolution.  Thusly we are using stepper motors for both axes.

The end goal is to drive the spindle and the C axis simultaneously, but specifying a relationship percentage for their rotational speeds.  For example,  Is there some documentation I can read which describes 

1. How to setup LinuxCNC to treat the C-axis as a secondary spindle, and
2. The G-code I would use.

Apologies if this is already been asked and answered:  I searched the forum and could not find it.

Thanks for your help, I used the output from lcec_configgen and replaced all the BLANK halType entries as S32 or U32, but now I get other errors, am I missing information in the xml file?:

I am way to ignorant on linuxcnc to understand what to do next. They are cia402 drives (Lichuan OL3-E57H) as I have two of them I have started with a lathe config as shown on the first video of this thread. How is the ESI file different from what linuxcnc needs? Should I be using output from pdos as my xml file?

That xml file is an ESI file. It will not work. See my reply above.
Run "lcec_configgen" and put the output into ethercat-conf.xml.

Can you post your hal file?
 

please see attached files

It is suport step/dir sir?? Because original stmbl are suported right, if posible open the step/dir interface mate, so we can used for mach3 or grbl, thank u somuch.

I'm running LinuxCNC/Axis 2.9.0-pre1..... on LMDE 6, using software stepping. I have a 3 axis CNC, with two motors on the X. Initial condition has the motherboard parallel port controlling the motors and a second parallel card doing some other details. One X motor works, the second does not.

I was trying to connect my g540 disable to the parallel port and one motor quit working, the 4th axis on the g540 (which is my second X motor, see image). Using an oscilloscope, I can see step/direction for the parallel port pins 2,3 (x) 4,5 (y) and 6,7 (z) when I use the arrow keys. Pins 8,9 have nothing when I use the arrow keys for x. I  figured I had blown up the parallel port, but somehow just those two pins.

Bought a PCI parallel card, changed stepconf to use that card instead of the MB parallel port. Same deal, I can move the X motor but the X2 motor doesn't do anything. I measured the new parallel port pins, same result. I can measure step/direction for pins 2-7, but pins 8 and 9 do nothing.

Somehow the signals on the 4th channel, pins 8-9, is not getting through. I think I have Stepconf set up right, it was a working machine before.

Help will be greatly appreciated!

Hey, i have a question about configuring a 6axis robot arm with lcnc, ive built myself a robot arm and im trying to control it via a puma560 simulation config, ive seen a youtube short of someone doing exactly that but he has no documentation on how he did it, im new to lcnc so i dont really know where to start with configuring physical pins, for context im using a rpi5 and want to use gpio pins for step/dir, ive got some tmc 5160t drivers to work and i get motion from them i just dont know how i would assign physical gpio pins to the already existing config Below ive linked the short where a robot arm is controlled by the puma560 config, if you stop at the right time you can see the tab name: youtube.com/shorts/js6OaVhUN2U?si=68d75rJqwbvCr9V0

Is the void lock disabled?
Old info, but had this happen often on PlasmaC while it was still being developed, does require setting VAD at under 75% and disabling void lock.
Did not happen probably last two years.

Also does absolutely require monitoring the voltage, as it can be caused by the plasma source dropping the voltage due to heat or mains voltage going up (transformer plasma) or issues with current control (inverter plasma).

Thanks Tommy. We had not discounted plasma voltage changes and had some ideas to check if that is it.

Good quality and cheaper than china, vertical machine torch is 40E in Germany, with 5 meter cable is 90E, bought both.
Mind the pilot arc, there are some without it so do not get those, it is easy just look for a red knob on the bottom front and usually it is written in spec info.

Hm, the issue is that I only have a 12 slot tool rack. I machine wood and metal and have my tool library imported into fusion as well. This means I will be switching tools in and out the tool rack as I need, so it would be great to use the assigned pocket numbers.

Nevertheless for someone not needing to change the tools frequently (or is more flexible in tool numbering) that is a good idea!

You can use tool numbers instead, pocket numbers have to be the same as tool numbers for non random toolchangers

Hello Klopp an ProG.

I'm also in the same situation to retrofit a Weiler 160 CNC. I'm very interested in the LCNC config files and also the classicladder for the turret. Can you help me with these files?
