General Mach Discussion / Re: Torch Height Control Issues – Are my SheetCam Post Processor commands optimal?
« on: March 22, 2018, 02:30:30 PM »
The good news is it had nothing to do with my hardware or post processor commands. All of that runs fine, no configurations changed since original purchase and setup.
The main problem with my machine is that I had little to no water in my table. (I am semi-retired now and moved my machine to my home shop. In doing so, I added heavy casters to the legs and push the machine outside to do all my cutting. The water made the table too heavy to move and I didn't care about the smoke as it was outside. )
After a lot of frustration, I added water back to my table, and most importantly, fill it to the top of the slats, until its about ready to start overflowing onto the floor.
With that done, as my torch tip begins to wear, causing the symptom to resurface, I'll adjust my pierce height lower. For example, cutting 12 gauge mild steel with 40 amp tip. The A60 pierce setting should be 0.18. When the machine quits working, I change it to .14 and it starts cutting again. As the tip wears further, I'll go down to 0.12, 0.10, and so on. I've gone as low as 0.07.
With keeping the water level at its maximum height, my machine is running great again. Just make the occasional pierce height reduction and I'm able to get all my jobs cut with little delay.
Hope this helps. Took me a couple of months to figure it out. I'm cutting more steel now than I ever have.
