Personally I vote (Do we get a vote?)for a third printer port.... Can it even be done? Back in the old DOS days it could. With windows I am not sure. BUT,...
Only managed 1 test run, which was better than 1.85 but worse than 1.8 Checking some settings I then got a blue screen exiting ports and pins Mach2.sys ...
Mike, There's no problem installing a third printer port. I had to do it when I was running 3 different print devices on my system, by installing an I/O board...
If it is a drag cut torch then the simplest method is to use a solenoid controlled by the Z axis direction pin. Setting the Z axis depth and feedrate controls...
... Code set back to 1.6 level in threading for next release. We'll try another aproach.. Don't know what caused the BSOD, strange one there.. ... To get this...
Art, Running a part using the Dolphin/Mach2 setup. First time I have used this. State setup for pause at toolchange. When I run the following code I get a...
... Is 1.6 same as 1.8? 1.8 was very nearly there. If it was 8 revs 10 might do it? ... Nope neither do I ... What I'm trying to do is after running one...
10 turns averaging seems a lot to me. You will need a very stable spindle velocity to have a good thread... So you will need a sort of constant velocity...
... Many Thanks to Steve Blackmoor who sorted this problem out. I had minimum speed set too high on the logic screen. Due to using a custom screen the error...

Hi Art, I'm hoping you can help another software developer who is struggling with continuous velocity and move blending. Do you know of any good descriptions...
Les, one of the problems with keyboard scancodes is the difficulties to get multiple control devices at the same time. You get conflict if 2 devices uses the...
Hi Olivier, No matter how you implement keyboard/joystick inputs you are going to get timing variation. It is in the nature of Windows to do this. Direct...
Olivier, When threading capability with Mach2 was first mentioned I posed a question based on a hypothetical situtation, it went like this: My lathe has a belt...
Good news Les. "No matter how you implement keyboard/joystick inputs you are going to get timing variation. It is in the nature of Windows to do this. Direct...
<Soapbox mode> I personally think that using keyboard/joystick inputs for EStop, limits and referencing is a _very_ bad idea. Both USB and PS/2 are message...
Hi Servo. it could be a nice solution, but not very cheap neither available for every one. I'm sure we can get all the threading mechanism working with mach2....
I think you're both saying the same thing, but interpreting it differently. In a critical safety oriented situation, you want your tool to STOP. Anyone whose...
Hi Servo, I agree with what you say and a hardware EStop circuit that cuts the power is essential. If for some reason Mach2 does not see the EStop then you...
Oh, forgot something. Servo's right. If you have seperate homing/reference switches form your limit switches, if the software does not pick up the switch hit...
Thanks for the quick bug fix Art, I ran it up on the table and its just fine .. nice and smooth too. ... Ok, I use a proper machine torch and the arc_good...
Les, I have not actually checked multiple homing events for the purpose of comparing repeatable positioning. Once the axes have been homed, which in my case...
Les, for information i get 1/100 mm repeatability with my homing, using low cost optical switches and parallele port inputs. My reference switches are ...
John Prentice misinterpreted one of my ideas as if I was going to use my MPG dial through keyboard emulator pins. In talking to Servo, he points out that...
Olivier: It can be done with specialty microswitches. You are better off the way you are doing it with redunancy of a physical limit switch backing up your...

I am using one of Bob Campblell's boards on each of my two printer ports. Very nice job Bob! Unfortunatly that limits my I/O to ten pins. Will Mach2 allow me...
