Hi all,
Purchased and been using sheetcam for a month or so now, and its been doing everything we need at work and then some, but today there were two updates. The second of which has caused some issues. We have a self built cnc plasma that has been working perfectly with sheetcam up until now.
Firstly, the feedrate is only set once, for the first cut. So my post processsor which sets a higher feedrate for rapids and z hops overwrites this, and the cuts end up going way too fast. This worked fine before the update, it would use the proper feedrate during cutting. Secondly the tool off commands arent being triggered for the last cut like they were before the update.
I modified the grbl plasma post processor for this plasma. I tweaked the tool on and off commands but didnt touch the movement commands where the feedrate seems to be set.
If you post a copy of the post processor here or send it to me in a PM I’ll take a look.
Sorry for the rambling in the first post, I was a bit frustrated yesterday when I posted that leaving work, I’d spent ~4 hours trying to debug what was going on. The updates were I think 7.0.6 and 7.0.8 I think, if that’s relevant.
The first file is what I was using for the past month or so without problems, I’ve tweaked it for a work around (the second file).
M10/M11 are the M-Codes I added to turn on/off a height controller I built for the machine, and M100/M101 turn a Z probe on/off.
As an aside, how do you add start/end codes for path rules? Adding a rule, there is nothing under the drop downs for start/end codes, and the three dots (menu?) button doesn’t seem to do anything. Where/how do I add start/end codes?

Sorry for the ramble and attitude in the first post, I’d just left work after spending a fruitless 4+ hours trying to debug what was going on.
The updates were (I think, it’s hard to remember, I did a few uninstall/reinstalls trying to fix the issue) 7.0.6 and 7.0.8 if that helps.
The post processors are modified from the GRBL plasma one. The Plasma Smoothieware is the one I was using for the past month, and it was working with no problems up until yesterday. The Plasma Smoothieware Work Around is what I’ve just put together to try and make it work the way it did.
As an aside, path rules don’t seem to be put into the gcode either.
