General Mach Discussion / F for feedrate

« on: September 04, 2010, 01:56:49 PM »

Hi,

Confused: F commands; do they set an overall tool feedrate which is interpolated from the velocities of all axes, or can each axis have it's own F value applied to it? Somebody asked me earlier and I realised I didn't know.

Lithophane... learn something new every day. Do you have pictures, or links to pictures? I'm curious to see what you do...

I take it Mach3 behaves impeccably right up to the limit?

Thanks, that should be enough!

Hi,

This may be in the documentation, but in case it isn't,how many lines of code can Mach3 handle in 1 file?

Thanks Stirling,

I had thought of splitting the signal from the controller to 2 drivers, each with it's own motor. Probably with a line driver before the split. Would that get round the potential inductance problems? Keeping speeds low would be fine, but so would knowing I'm not killing my drivers...

I may just drive the whole thing through a screw, as the weight is beyond what the motor would like, ie 7kg vertical lift, albeit at low speed. Also the holding torque woyuldn't matter, as the pitch of the screw would hold it. That way I only need to use the one motor.

If it doesn't work, I'll be back!

General Mach Discussion / twinned motors; 2 sharing 1 driver

« on: August 07, 2010, 05:47:43 PM »

Hi,

I'm wondering what the problems are with wiring 2 steppers into 1 driver, and just doubling the current? I intend using a motor at either end of a long bike chain; the chain will hang very slack, and the 2nd motor is just there to stop one side of the chain clashing into the other.

The application for this is a revolving 'carousel' pen holder for a large plotter.

Only got 1 axis left in Mach, but 2 motors left in the box! It's tempting to try it, but there must be a reason nobody does it that way.
