Hi All

Been playing around with Mach3 and my new Taig for some time now but am having problems, i can jog my machine on all axis fine, everything is wired up correctly, driver test gives a clean line with only a few spikes now and then, am running a laptop Dell D600 1.6Ghz 576mB ram, but occasionally the motors just stall every time or they will miss a step.

Settings:

Running on 3 260Oz/In steppers, 50V Drivers

Velocity: 700
Accel: 27
step pulse: 9
on all axis

1/2 Sherline pulse mode is on
Went through Arts XP tweak guide and done all operations!

I took my Taig apart, cleaned and re lubed it, adjusted the gibs to a good spot i feel. When i come to machining a part it will stall either when it rapids or cutting at the calculated feedrate of 298mm/min through aluminium at a 1.5mm pass at 6900rpm. also all of the axis miss steps and mess up my expensive stock.

Can someone Please HELP AAAHHH!! lol

Regards

Hi all, hope everyone is doing well!
Ryan, try to set your velocity down some. Start off low and keep increasing till
you have trouble then back down about 20%.

Also try adjusting the acceleration as well - acceleration needs POWER - and if this is too high, to get to your 700 - the motors might just baulk at it.

I notice you have the step pulse at 9 - I thought the limit was 5 - but I'm not sure if it makes any difference.

You have probably just tightened the gibbs up a touch more than they were and this is causing the extra drag, particularly at the ends of travel, where there is less wear.
