Well the VFD does have a minimum speed. It won't run below that because of min speed and overheating. I did see a freq of 300 (18k rpm) on the HAL while the VFD locked up. Also MDI'ed S18000 in while the VFD was locked up. Looks like the watchdog_out to the VFD is a problem here. Danny

Entirely through Modbus, which otherwise works. I started from the wj200_vfd.c code and made some changes to make an x200_vfd.c file. Just changing a few coils. Modbus starts from the OB RS232 serial port and goes through an isolationg RS232-RS485 converter. Like I say, setup's been good,

It's every single time. If I use M3, spindle runs 100% reliably. Or, if I use my XHC wireless mpg, that runs it fine too. But on the Manual Control tab, there's a Spindle button with a CW button flanking it on the right and a CCW button on the left and +/- buttons underneath. Hovering over

Yeah I don't expect any immediate solution, but this is a significant problem which doesn't need to be. If you've done an X-offset by +2", then the limits check and live preview just needs to offset by +2". They don't need to recalculate every line of g-code. Unless, of course, you use a G10

Can the acceleration be changed dynamically through HAL and still work properly? Because say the traj planner looks 10 moves ahead, and it's 2x G1 followed by 3x G0 moves then 5x G1. It forms a plan based on the acceleration rules. But when it hits the 3rd command, the HAL suddenly changes

Hmm, interesting, but that's only to reduce accel in manual mode, right? It'd reduce shaking while using the mpg, but the G0 moves in the g-code would create motor stalls if used at full speed. I'm wondering if all G0 and manual input could be a mode of higher speed but more limited in

It's modbus, sorry forgot to mention that. What baffles me is the Spindle buttons on the panel, AFAIK, just map to the same spindle-run in the HAL that M3 goes to. I remember looking at the HAL monitor on this weeks ago and IIRC it was "spindle run true, but spindle-isrunning false". The

It's a direct dd copy of the drive. If that wasn't complete, a lot more would be broken. I would not dismantle the (mostly) working system like that. There's a risk of something getting stored wrong on the working drive while it's on the new machine, and I don't see anything to prove by
