General Mach Discussion / Re: Plasma cutter shuts off after 5 seconds

Never mind found out the torch shuts itself off if it does not make good contact within a few seconds.

General Mach Discussion / Plasma cutter shuts off after 5 seconds
« on: December 18, 2017, 04:37:53 PM »
Hello I am converting my router table to plasma, So far everything is going great except  my plasma cutter shuts off after 5 seconds, I have it connect from the hand torch trigger to my spindle start relay.     I can hear the relay click the torch fires then it starts to lower and then nothing, If the two wires going to the relay are crossed it will stay on all day.

If I reset the plasma cutter without doing anything else it will give me an error saying that the torch trigger is depressed during startup.

Need help making two sided cut on corbel, each is offset on the Y position when using deskproto or using aspire with a written code rotation between jobs.

General Mach Discussion / Rotary axis bug?
« on: February 24, 2015, 03:24:38 PM »
I have recently setup a rotary axis and have got everything to work properly except if I feed hold or e stop and then resume the y moves -6.5 and then it resumes cutting. Is this a bad setting or some sort of glitch??

 I know the code cannot call  for a y move because I am not using continuous 4th axis.

I have put in 277.7777 in the steps box,  sometimes it will spin but will not always turn the right direction, the rest of the time it will just growl and jerk back and forth, I have my acceleration at 15 and velocity I have been trying different numbers faster seems to work better but not properly.

Thanks for your help so far!

General Mach Discussion / Rotary axis setup help
« on: February 05, 2015, 03:39:35 PM »
I have read quite a few posts but am still stumped, I am setting up a rotary axis on my router table but do not have the steps quite right I believe.      I have a g203 with 10 microsteps and a harmonic drive rotary with 50-1 reduction. The numbers I came up with is 222.222  and .0036  The first one makes it turn fairly smooth however sometimes when I am jogging it goes the wrong direction,  the second number .0036 just makes it growl.  Also when the axis indicator rotates once the chuck rotates about 5 times.

Chuck type: K11 100mm three jaw centering chuck

General Mach Discussion / Readouts scrambled on mach 3
« on: June 10, 2014, 08:30:51 PM »
Hello I am having a problem with mach the feedrate and dro readouts, they are all scrambled, instead of Z+1.5 I get Z+224.56 or something random the feed rate display is also messed up showing huge figures.  A restart does not help the situation at all however it works perfectly other wise but this is annoying. No changes have been  made recently, I am using smooth stepper but have not had problems with it.
