General Mach Discussion / Re: Plasma , cuts offset problem

« on: January 02, 2017, 12:34:16 PM »

Then the issue lies with sheet-cam somewhere. Can i suggest the sheet-cam forum as a source for more help, may find the answer with a search. I'm not aware of a setting that stop all offsets working unless the post is the wrong one maybe?

I presume you have set up the tool as a plasma/jet tool??

0.0625 should be good for a start, but if its not offsetting something is wrong.

Try creating the same job with the offset in all settings - inside, outside and none then compare the code visually, its should be obviously different in each case.

Looks functional, nicely put together, well done on the build.

Re the axis flying off in the event of a switch fault - best solution is to fit hard stops, these may be plates, brackets, long bolts etc. Being a stepper drive system no harm will be done if the axis ploughs into a stop occasionally - mine has several times. Having the gantry fly off possibly with a running spindle and tool could be nasty as your instinct would be to try and catch it.

How wide do you have "Kerf" set in sheet-cam?

If you cannot move at faster speeds with the vise mounted etc then you have exceeded your machine's capability it seems.

The only option would then be to fit bigger motors, drives, power supply and so on.

The best thing to do is to tune your setup by increasing speed until it skips steps/loses position, then decrease speed by 30% and increase acceleration until it fails again then drop 30% - this should be close to your machine limits based on motor power/ weight/ drive system etc. Tune with the vise loaded of course.

It may be possible to tune in such a way that you can do the job needed but at a lower pace than wanted or required by tool specs etc.

Follow Twekies advice, he knows far more than i ever will

You have said you were cutting a hole and it came out twice as big - you have not said how you coded the path - manually, CAM, wizard???

No help can be given in such vague circumstances.

If twice the size, are you sure your units were correct - inch / mm ?

Or were you entering the diameter when it needed the radius?

SS relays are great but always remember that when they fail, they generally fail short-circuit or permanently on, never use in safety circuits.

Usually abut 5mm less than table limit switch setting seems to work, if you get  too close it can trip the limit switch.

Hmm, but if the compiler is kaput as it won't run the m3.m1s will it run the custom macro?

Would it even run the macro pump?

Maybe this is why nobody has trapped this intermittent bug??
