27 Dec The breakout board is a DB and I have found very little about people successfully using one of these boards with LinuxCNC.I have laid. 19 Jan Just a quick newbie question. If I want a 3 axis with 2 steppers on x. For a total of 4 steppers, can i hook all of them up to a db breakout. 20 nov. Je me tourne vers vous car je recherche un shema pour raccorder 3 Stepper motor driver DMA, PEAK A a la BOB DB et les.

Once I had remembered this step i used a test db25-11205 to verify that the outputs on the breakout board db25–1205 responding to the test on the same No pin of the port,which reassured me that both the cable and the board were working. LinuxCNC and DB board If anybody is interested,I checked out all the pins on the back of the computer and they all passed current when the test utility was used.
Hmm, probably not just electronics, but I’ll stay on topic.

Does this make sense to anyone? The next challenge is to make them move the distance they should according to the g-code. Old router build log here. Its possible your step pulses are too short to be passed through the very slow OPTO couplers on the board. El Beast – Initial design phase, The time now is I’m currently working on my driver box and it seems to be going okay thanks in no small part to Clive.
Set the step outputs to ‘active low’ – thanks again Clive for dv25-1205 out how to do this: I will try again with a G64 manually inserted in the program and see what happens.

When the high electrical level is active, all control negative db25-205 will be connected together to GND. When low electrical level is active, all control positive signals will be connected together to public port.
I’ll email the supplier and see if there’s any info. My question is how do I check whether the parallel port is working as I haven’t used one for at least 9 years and the old computer that has one doesn’t necessarily still have a working port. Regards the wiring then Yes the diagram is correct and will work.

Which I guess translates to: Any advise on that. Lathe build log here.
How can you be sure that this is the case? Denford novamill linuxcnc retrofit Can’t see the Linux link but again I’ll take a guess.? That’s mean the board drain power from lpt and not from external power supply 5volts witch is still off.
What are your thoughts guys? If you cd to Downloads you will find the port test utility you downloaded by following the earlier link. Follow us on All times are GMT The next challenge is to get the machine moving as it is supposed to do. Broken lpt port, or breakout board.
I can’t see why it wouldn’t, but there’s the duncery kicking in again It allows you to tell linuxcnc how close to follow the programmed path.
Now to return to the control module and motor wiring. Looks like I will have to select “other” and go through the connections one at a time until things happen. Results 1 to 7 of 7. Now I have calibrated to this,the basic movements are correct.
