Good day

Struggling to find a new pc with LPT ports.

General Mach Discussion / Oval holes
« on: March 22, 2017, 01:06:09 AM »
Hi, my plasma is cutting oval holes, why? the x and y axis speeds are the same, I also calibrated my machine twice and still have the same problem. I also changed the speed in motor tuning with no change, accept that my cut sizes where either to big or to small. please can someone tell me what to do.

Hi
I have questions and no answers, first I have a pierce limit problem, I was told to check posts and could only find posts in sheet cam where I set it to 1000, I'm still only piercing 10 times before I have a m01, where do I set this pierce limit in mach?. I did post answers to questions but only find them when I do a such under Marshall, I thought pierce limit was solved, sorry I was wrong on that, but the pierce delay problem was solved after I entered a larger number, thanks. My other question was where should the earth be on the table or on the job, since I use a waterbed and have no space on the job for the earth I put it in the water on the table, would this be correct. Then i have a font problem sheet cam does not recognize all fonts and TNG not all symbols in text like "&" how do i solve this?.

We bought and build our own machine that works just fine except for a view points here and there. We are using a thermotech 1650 series 3 plasma machine with automatic thc and air only, we are cutting mild steel and thinking of stainless, I do dwg. in Auto Cad Lt then save them as dxf files and then open them in sheet cam and then sheet cam saves a tap file in mach 3 from where I do my cutting proses. I would like to know where the earth should be on a waterbed, I shall add a photo of my machine, I am using fine cut consumables and do get excellent results, but i can only pierce 9 time then mach return on a m01 optional stop, where do I make a adjustment to increase the no. of piercings. My next problem is that sheet cam does not recognise fonts like stencil although it opens the dxf it only display new roman, also the pierce delay is not working or not responding to the setting made, example, when I cut 2mm cold rolled steel I set pears delay to 4 sec. and that is good but when I cut 10 mm plate it refuses to delay I can set it to 10 sec. it starts moving the second the torch starts.

 Appreciate the help.

I have a problem setting the no. of piercings my machine does before returning on a mo 1, where do I change this setting and to what, currently I can cut 9 holes and it will return on a mo 1.

also please tell me is it essential to have the earth on the job it self or can it be on the cutting table, and if I made a water bed does the same apply,

I also have a problem with sheetcam not recognizing fonts, I use auto cad 2000Lt and are able to draw dxf fonts like stencil but sheetcam does read stencil
