Am I seeing right? Were you yourself able to update your thread title to show SOLVED?
If so, I didn't know we could do that.
I like it if we can we now change the title of our own threads when appropriate . . . .

Thats the dude lol

[woodworker]

yeah just edited the title :) useful to know

All licensed up now for a full test, if anyone else is after a full Mach3 License
cheapest I found was low cost cnc retrofit they are in Australia but as its a download it matters not, took about 8 hours to get not bad considering the time difference its $145 instead of $175 on the Mach3 site. I emailed Artsoft querying the price still waiting... Low cost are on their list of resellers.

Ok, now you have a genuine license, I would recommend that it is registered with ArtSoft, then if you lose the file, you can re download from ArtSoft. That got me out of the shit after I lost my hard drive and the backup had failed without me knowing it.

My next task is to take a back-up of the restored system and check I can restore it to a fresh hard drive - and get it working from there.

Sadly after all that turns out not to be software, I was happily cutting away this afternoon when I watched the movement stop yet the code continued to run on Mach3 then it the machine moves again of course out of sync with the code, this is obviously an intermittent fault and seems to be on random axis anyone have any idea how I can track this fault down, I'm about ready to skip the whole thing.

Think I will get murdered by the Mrs if I skipped it lol, the control box is a Rhonmac not sure on controller cards etc all in a nice neat box, I have noticed that when I jog the motors usually first thing they just make a noise and dont move obviously if this happens mid cut it would cause my issue, but so far I have been unable to hear the noise when its all running. I'm wondering if its to do with the speed I have it set to?!!
not really sure if the settings are correct my machine info is 1600 steps 8 micro steps 15 motor teeth leadscrew 30 leadscrew pitch 2mm expect this means something to somebody. Mach 3 is set to steps per 2000 velocity 438 acceleration 187.5

[cropwell]

It could be a motor stall problem. Try reducing the acceleration, you can always set it back up if no difference. Your Mach3 steps per looks wrong. I am very tired at the moment, so if anyone would care to check my calcs please let me know if I am out.

Motor has 15 tooth pulley, Leadscrew has 30 tooth pulley (I would have expected this to be the other way round - but no matter)

2:1 pulley reduction
2mm pitch leadscrew means axis moves 1 mm per revolution of the stepper, ie 200 steps, 8 microsteps means 1600 pulses per rev, i.e. mm.

So steps per in Mach3 should be 1600 not 2000.

Have you done any dimension tests yet or has your current problem overshadowed things ?
