New CNC machine with RS232 (plain serial) connection to PC!!!

Category: Show Your Stuff

Feast your eyes and marvel at the modern stupidity i was faced off with today, a new (2024) CNC plasma cutting machine using RS232 or plain old serial at 19200 baud to communicate with the PC, running windows 11 while machine controller running in 32 bit mode!!!
Hypertherm PowerMAX 65 attached to the same box as the PC, with the same DB9 connectors that were inadvertently plugged into the wrong places. Plain simple stepper drives and motors, THC with Ohmic probing, toroidal transformer, etc, or the usual.
RS232 is very flaky at the best of times, but today besides the win s#it, it worked after setting the baud rate and stop bit and flow control.
Considering myself lucky! :)

Using a servo as a spindle and positional axis - keep getting vague errors

Category: Advanced Configuration

This setup works for me. My servo is a LICHUAN, so you need to install the caxis.comp and gn_userkins.comp components, create a remaps folder, and save the two ngc files there.

Mesa 7i95T can do step/dir and encoders on one board.
And just to make sure, take some pictures of drive to motor wiring and post them here so we can confirm it is OK, preferably before powering on the drive! :)

Moving robot joints by only 1 Gcode command?

Category: Advanced Configuration

After trying this idea, i faced another problem: every time I stop the program during movejoint command. The controller doesn't return default kin, I have to use M code to switch back manually, I tried to hack into the controller(the command.c file) to force it to return to default kinematic every time I hit stop or estop. tks, it worked

I have the same machine and was wondering if you would share your info on the motor and drives. I have the 7i97t and trying to figure out where to start.
thanks

I Agree with you regarding the Optimisation of the dynamic range (headroom) of the AD converter.
will double check all the machines most of them are hyperterm 85, 105,125 and maxpro 250.
so I need to check max voltage and select the proper divide ratio

Encoder on 7i95t

Category: General LinuxCNC Questions

Did you first verify that stepgen feedback worked?
(scaled properly and motion in the correct directions)

That is replace:

net joint.0-pos-fb <= hm2_[MESA](BOARD).0.encoder.00.position

with:

net joint.0-pos-fb <= hm2_[MESA](BOARD).0.stepgen.00.position

Once this works, I would verify that the encoder position is also in the correct direction
and scaled properly.

Also note that for initial tuning with encoder feedback, you will need to widen the following
error limits and reduce the P term
