Hey Everyone, after months of my Cross fire pro sitting doing nothing due to a new born Son I have had time to head out and attempt my first cut. Lets just say it was somewhat disappointing and very satisfying in the same breath. I am as green as they get when it comes to plasma CNC cutting. Tig Welding and general metal fab no worries !
I am using CAD for my design, then sheet cam for my G-code and finally crossfire. I am running a hypertherm 45XP with machine torch and Plug and play CPC cable. I have all my cutter tools set at the Hypertherm cut chart recommendations out of their manual.
There is a couple issues going on but can anyone take some time and give me a few pointers ?
1 - Voltage warning - came up twice but not on 3rd attempt ?
2 - Not completing all the cut ?
3- Cut settings seem incorrect but taken straight from hypertherm manual ?
One thing the I saw in your video. When the torch came down on the left side it tipped the piece of metal, the metal moved and the initial height would be wrong.
I see pierce delay way to short
I think your cut speed is too fast.
Make sure your work piece is properly supported to prevent tipping so the height control is sensed properly
The cutting tool files I actually downloaded off this forum from another member !
@73cruiser I did not even notice the pierce delay was incorrect decimal place. I will also try and support the material better, at the time of testing that’s all the plate I had to cut.
I have since made my own cutting tool files for sheetcam ( in metric as I am from Australia ) so will give everyone’s recommendations a try today.
hahahah ! how cant you laugh… in my head I had pictured this perfectly cut plate, then Bang !!!
Thank you Keith, it has been a hectic 8 weeks as others will know with a young kids… Every time I try to sit down to do some reading. Nappy change, Feed etc !! hahaha.
BUT !
Had another crack this morning after creating my own Tool set in metric ( Hypertherm manual specs )
I did get the Voltage warning again on first attempt but went again and was fine ? seems random when it happens at the moment !
The letter work came out pretty nice for 8mm thick plate, standard hypertherm consumables
I understand the cut out in the o on the video, but it looks like there was a cut or pierce before that as well as a cut down by the c at the start that probably aren’t needed. Might want to look at the file a little closer. What programs are you using ?
