Trouble with dual motor gantry setup

Thanks tommy will try that today. Lots of work, so little time ...

Rod, what is the cost of the Mesa card

Ok got this working. I realised that the files I gave you were the ones in the middle of me testing.

The problem ended up being an IO Error (as in Idiot Operator). At the start of the linuxcnc change we decided to fix an issue of the previous setup, in that the longest axis was Y, not X, which is not particularly intuitive. I switched this round every where in the hal/ini files but forgot the wiring diagram from before still had the old parallel port pin setup.

Therefore it was hitting the X-Limit when trying to home Y

All homing seems to work Ok now, thanks for all the help.

Am now moving on to the vfd using the hy_vfd over modbus.

All the comms seem to work ok but when the spindle starts to spin I get joint limit errors on all 3 joints
I have look at halshow and dont see anything strange. What I have done is to disable the pwmgen stuff in the main hal and added the attached custom.hal.

Will research it tonight but thought I would post this to be sure that I am not doing something stupid

That is a grounding/shielding issue, make sure the PC and the machine electronics and the cabinet are properly grounded.
Do not continue without fixing that, it usually adds another PC to the dump.

yeah that makes a lot of sense. Will check it today.
