It was the Z axis, Wojtek got back to me saying the macro needed a sleep 1 between While IsMoving() and Wend. First I have heard of that but he said it was overloading the PC because of the lack of sleep.

Also remember this is not the IP-A so no encoder feedback and that was why I was struggling to see how there could be a epid error as I imagined that would be due to the closed loop of which the IP-S does not have.


Anyway going to reinstall Mach when I get a chance.
Got my BobCAD post altered last night for the plasma and it is looking good so far :)

Went to cut a strip off some stainless today and one of the drives has died :D Or at least I think it is the drive, potentially could be a short in the wiring somewhere but unlikely.

Have some spare drives  here at home so not a huge problem, transferred the drives settings file over to one tonight and  will get it swapped out tomorrow.

Dead Drives = Expensive


Spares, PRICELESS

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

LOL, all mine are second hand, don't pay huge money for them, bought two 1Kw ones maybe 5 or 6 months ago as I  had used the last of that size I had on the plasma. Got the 2 for £150 which is more than I usually pay but they are getting less common on eBay now.

Well put the spare drive on and all is fine :)
One thing though, I always thought the square side of the cut due to the swirl of the plasma jet, was right hand side as the cutter moves away from you. This seems to be the opposite, I cut an internal circle and if I go anti clock that should leave the edge of the hole square and the scrap bevelled but for me it is the opposite, go clockwise and the hole is straighter and the scrap bevelled.
Have I got things wrong or are the Trafimets maybe different?

It all depends on the angle of the holes in the swirl-ring in the tip and if the electrode has a swirl groove like on the Hypertherm electrodes.

Must be Dave although I am not even sure if they have an angle on the swirl ring holes, will have to inspect closely but they look straight although common sense says they can't be.

Just had a closer look and they are angled.

Yep, the Hyper electrodes also have a very coarse screw thread up the side but that is also part of the blowback start i think.
