I have a lathe project where the operator wants the zero position to be in the middle of the chuck and the home position to be at the beginning of the travel where the home switch is. I currently have it programmed to perform a home search move until it hits the home switch but then the zero is not in the center where they want it. Is there an effective way to do this without installing a switch in the middle of the travel? thank you

I was able to make it work using motor[x].compPos

Im wondering the best way to be able to add a tool offset on linear axis I can seem to find the correct command. For instance a tool with a .1 offset should be able to input .1 in the axis offset and the position will stop .1short.
Thanks

Hello,
I am wondering if anyone has any updated lathe.g files with updated syntax for power pmac ide.
thank yo

We were told when we ordered powerpmac that there was a lathe function in the default project. It looks from the Gcodes and NC software like it is set up for a mill.
Is there a base project with lathe functions instead of the default mill?
Thank you

Im having trouble getting it to work.Are you sure its in the default project? All the Gcodes seem to be for a mill application. We need it to be for a lathe.
Thanks

Has anyone had this issue before? We have an hmi communicating to power pmac through a modbus tcp server. Whenever we use an input on the HMI the program buffer must get wiped or something because when cycle start is pressed the program wont run unless it is redownloaded.
And idea how to get around this?
Thank you

Wondering if anyone else has had this issue before. The x-axis in our 5 axis cnc lags behind by about a millimeter when following the TCP. The motor position shows a 1mm following error which makes me think it knows where its supposed to be but isnt keeping up for some reason.
We tried adjusting the tuning and proportional gain settings which slightly decreased the error but its still to big for the applications we need.

Any idea where to find the ESI files for the Servotronix CDHD drives?

We're building a CNC lathe but the only options in the config file are Mill or Laser. Do I need to buy a different version to get the lathe option or are those the only two available?

Tuning seems fine and it has no trouble holding. I dont see any torque spikes when I jog it normally. I have noticed sometimes the softlimit bit comes on even if its not near any of the soft limits set which is interesting. I will check feedrate and look at doing an open loop test. Thank you

Sorry I just meant the status bit saying the amp is enabled or not
-
Having an issue where I need to enable the motor twice for it to work correctly. If I send a command "#1j/" all the status indicators are green and everything seems fine but when I jog nothing moves. So have to disable and enable the motor again and it will work correctly. Any ideas what could cause this?
-
May need to check coordinate system settings. I know cycle wont start if motors aren't closed loop and homed.
-
Update.
It was an abort deceleration issue in a couple of the motors. I just had to adjust Motor[x].abortta and Motor[x].abortts
-
We have a bug where the only way to start a cycle in mdi or auto is to jog in manual first. Any one run into this before?
Can't Spiral down with G42 comp

Im getting the same error with cutter comp. Try it with G18 or G19. I have an XZ lathe but it would only work with and XY plane. Still working on figuring out why.
