General Mach Discussion / Re: Mach 3 bob help

Hi Naeem,

I am concerned that you BoB is extremely dirty and that the contamination may be electrically conductive - if the same applies to your PC (or if your PC can become contaminated in the future) then you are jus heading towards failure. Sorry to be so critical but unless you tidy everything up first (the soldering and twisted wires are a joke) you stand little chance of achieving any sort of reliability from your plasma machine.

No. have them set at 1A, stepper controllers can go to 2.5.

That is Current - What Voltage are you running your steppers at ?
Are you running them at the maximum Voltage that your drivers allow ?

(basically Current determines Torque and Voltage determines Speed).

I tried you suggestion and X1 did indeed move by 1 mm, it took fifteen seconds though.

When MDI testing type G0 X1

If necessary return to Motor Tuning and adjust your Velocity and Acceleration settings to set the axis speed then save the changes.

Hi Peter,

MDI only seems to work in inches, regardless of settings. i.e. with everything set to mm, an input of X1 in MDI caused a movement of 25.4mm, not 1mm as expected.

Assuming your above measurement is accurate then the simple answer is to return to Motor Tuning and for each axis, divide your existing Steps per Unit by 25.4 and save the changes. Now when you MDI   X1   the axis will move 1mm.

General Mach Discussion / Re: I need help with e-stop

« on: May 13, 2020, 07:22:45 AM »

Look at the EStop switch on your machine - if it has a spare (unused) set of contacts then connect them as Graham has suggested. If there is not a spare set of contacts, could you fit a new microswitch which is operated by your machine EStop switch ?  then connect that switch as Graham has suggested.
