General Mach Discussion / Re: problem with mach2

Jaime,

It’s a long shot but something additional you may wish to consider…

If you have one, try replacing the BIOS battery and reconfiguring to the optimum settings for your PC, graphics card, etc.(when these batteries go down, the BIOS can reset to default or cause other strange problems with a system that has previously run perfectly).

Hi Mike,

Adding a laser to an existing machine is not difficult to do but it does entail quite a lot of work so perhaps it is best left for the winter months. 
It would be great if you start a project build thread on this – I, for one, look forward to following your progress.

Mach3 and G-Rex / Re: I have installed Mach3 Mill and the software stays in the emergency mode

Stefan,

Assuming your machine has an EStop button then check that you have the right configuration for it (active hi / low, correct port and pin etc.).

If you do not have an EStop button fitted - you should really fit one but in the short term...

Choose 'Emulated'  for your EStop configuration (Config / Ports & Pins / Input Signals). This should allow the on-screen RESET to be reset.

If the circuit which you are connecting the TTL output to applies too much loading and the TTL voltage is falling then perhaps consider including a simple transistor driver.

Hi Tim,

To run Mach3 successfully whilst using the parallel port you need to be using a PC (laptops seldom work well).
If you download and run Parmon http://www.geekhideout.com/parmon.shtml this will identify your parallel port address and allow you to test the port for output and input.

Thanks Mike.

I had to do a bit more acrylic cutting so while I was at it I made this - one can only dream.

General Mach Discussion / Re: How would you trigger a recripricating air operated dot peen marking head?

« on: August 03, 2013, 02:19:36 AM »

Nate,

The digital trigger output pulses from the Impact / Laser plugin consist of two parts, an ON and an OFF with a maximum duty cycle of 50%.
Many have successfully used this plugin with electromagnets so I see no reason why it could not be used with an air operated solenoid.

This and other linked threads relate  http://www.machsupport.com/forum/index.php/topic,20490.0.html

Hope this helps.

Don't pay too much attention to the "Port 1 Pins Current State" LED's - they seldom work correctly, if at all.

The "Input Signals Current State" and "Output Signals Current State" are what you should be guided by.

Hi B,

Please keep us informed of the progress on your own designed PWM speed controller. Once it is all sorted I am sure others would be most interested in the circuit details etc. if you are happy to share it as a project.
