Thanks Terry - sometimes I live in a totally different world

I suggest that you try changing the Kernel Speed to 25k, restarting Mach and retuning your velocity settings for maximum reliable motor speed and save these settings.

100k is really not the best setting for performance and, depending on steps per, it is unlikely that it is ever necessary to exceed the 35k Kernel Speed.

rrc1962,

The carriage return is necessary as the final line to get the M30 to rewind the code ready for the next run. Adding the % as the final line provides this.

I have run this code some 30 odd times now (till I got fed up) and not had a failure.

Incidentally what is the M1100 and M1101 supposed to do ?
What do you have in your M11, M1100 and M1101 macros ?

Looking at that video, the motor is stalling. Reduce your Velocity in motor tuning until you get it to work reliably, save the result and try again.

If I run at about 1000-1500mm/m, then it seem fine.

I think you have answered your own question here. 

You could do as Gerry did (at least I think it was Gerry) and find a local computer supply store, take a copy of Mach on CD and explain that this is the program you want to be able to run and if the Driver Test works OK on their recommended computer then you will buy it. If they don't want to play ball find another store.

Hi Bob,

One wire from a  capacitor goes to the same terminal as the switch is connected to and the other wire from the capacitor goes to GND.
Fit one for the EStop wire and every other limit switch that you have connected. They are fitted at the controller end (usually the breakout board).

If you post here or email me a copy of your wiring diagram I will indicate where they are fitted if you are still in doubt.

What do you have the Kernel Speed set at ? (Config : Ports & Pins).

Bob,

Length of cables are an issue but as long as they are screened and correctly terminated you will be OK.
Limit switches must be connected with screened (shielded) cable with the screen connected to GND at the controller end only. A single point GND for all common connections is also good practice.

That's the ones Bob.

Packs of them are available on EBay for small money.

No help at all but this type of problem is occurring more and more frequently as the old technology PC's with parallel ports and WinXP are starting to become scarce. The future of Mach will perhaps lie in 'external motion controllers' but which one is best to use is anybody's guess.
I have one machine running with the Smooth Stepper and that works just great but from reading other threads I see it would not be suitable for all machine situations.

Anyone else have any views on the future for Mach (except that version 4 will solve everything) ??
