Hi Richard - not sure if you are still looking, or if you have taken the plunge by now !

We have a PFM 750 machine with a four axis BZT controller. It's running a bespoke cutting head for our...

Also - keep your eyes open for companies that are using pick and place machines/robots etc, as they may have old kit that they are scrapping and you can salvage some from there. Take the cables too...

If you're looking for a reasonable MTF (in industrial terms rather than DIY/hobby use) then something like the IGUS energy chain is probably the best way to go. At my last company we specialised in...

Thanks for the suggestions - it's quite a curious one. Pressing the button a second time after the button has been pressed to interrupt the program and return the head to machine zero (which it does)...

We have a machine that runs in a production environment, and we have sorted bespoke screens which are working well in the main. One problem is the button code to interrupt the process sometimes...

Yep, that's worked a treat !

Thanks

Thanks, but the line with sleep on it always results in an error ?

I'll give it a go without the declaration

Tim

I've tried adding the code as below into my macro to interrrupt the current program and send the machine back to a safe location, but I get a type mismatch error on the "Sleep" lines. I've tried...

Spot on - I've just looked in device manager and it's not there ! Not sure why, but I'll have a re-install and see what happens.

Tim

Yep, a macro to change the screen would be just fine. I'm exposing the limits of my ignorance here, but is there a way of attaching a macro to the screen so that it runs once when the screen is...

Thanks - screentweak was just the ticket !

Tim

Is it possible to run a macro when a screen is opened ? I have a row of four buttons that load the four Gcode files that the user will be allowed on the machine, and a row of four userLEDs that...

Hi ! I've been playing with designing a new screen for a piece of kit that we will be putting into a produciton environment, so have minimised the number of buttons/etc. I've been working with two...

OK, I've been working on this long enough now. The code works fine from the button on the desktop machien running the system, but will not run from the button on the laptop development environment....

OK - not quite sure what's going on here, but I noticed that the VBScript buttons on the other screens didn't work on my laptop development environment either. They do work on the desktop running the...

Thanks Gerry, but I've tried DoButton and DoOEMButton, I've tried with spaces around the numbers and without. Even putting just one of them in the code window doesn't work. Putting just the number in...

I'm struggling here, I'm looking to create some very simple screens to run a bespoke machine, but the code for my buttons is refusing to run ! The screens have been created in mach3screen 2.7, and...

Thanks for this, my syntax was a little wrong. However, I've been banging my head against this wall for a while now, and can't make it work. If I run the script line from within the button script...

We have a very simple application for our machine, and the operators will only need to select from four pre-prepared gcode files. I'd like to simply drop four buttons onto the screen, one for each...

Certainly it's the first thing I'd try. The new card was less than 20GBP, and I'm sure if I'd tried I could have found a cheaper one.
Having now tried two Compaq Evos (company has a stock of them !)...

Just to let you folks know - Its working now !

I tried pretty much every adjustment I could find reference to for the compaq evo that I was using. By this point I had a clean XP pro install with...

We're running Mach3 on a Compaq evo P4. After some poor initial performace running steppers I looked at the signals at the parallel port. The pulses are not regular when viewed on a scope. Seems that...

Thanks for the suggestions folks, I'm going to start a new thread with a new title, as this issue is PC/software based and nothing to do with the mechanical arrangement or motor/drive/feedback.
The...

OK - more info ! The issue is definitely related to the PC end of things. I've had a chance to get a scope on the port and the pulses are all over the place. It seems as if there are some (around...

The machine is driven with steppers, and no feedback, so I don't think that backlash can be a factor. The issue is apparent with and without loads applied to the motors.

Tim

Thanks Tom, I'll check through this.
The motor wiring is a little difficult to trace, but it looks like this:
the drive has four outputs, labelled A+, A-, B+, B- (no surprises here)
These are...

Thanks for your thoughts Torchhead. I'll try to answer as best I can -
We provided a PC, and after several seaches around the web for advice settled on a stable PC (Compaq pentium 4) with a complete...

Hi ! We've just had our gantry mill delivered from BZT Germany. It uses Leadshine 2278 stepper drives and has been delivered with Mach3. We've switched it on and started running through basic checks....
