Would love to help and I will do my best but I'm not shure if I can. Never actually got to finish that machine...

Found the problem. The drivers for the parallel port were at fault. The website didn`t provide with adequate ones so I downloaded a free program that found the drivers for me. Now it works perfectly....

Using a desktop intel xeon based PC with nvidia quadro graphics card. Its old but still powerful and no it doesnt have any energy saving modes like a PC. And unfortunately I cant seem to source one...

Changed it to 5, 10, 15 no difference. Now the Y axis whines again and doesnt have torque when idling.
I suspect that the controller and mach dont have anything to do with the problem... Because...

I just changed the kernell speed to 60 000 Hz now X axis doesnt whine but just twitches at the start and then loses the torque the Y axis works as intended and the Z axis works but whines.
I have 3...

I have no idea where to set the PWM for the steppers. I have the step and direction settings. The PWM settings are for the spindle?

And sorry forgot to post the tipe of motors and the power supply.
Motor: HS2328A NEMA 23 2-Phase 400 oz-in (2.82 N.m) High Torque Stepper Motor with 0.25'' Single Shaft
Power supply: Leadshine...

Current set to 3A RMS Peak 4.24A. Read the manual changed the setup time a million times to various values, makes no difference.

The Z axis worked fine with 4000 steps per revolution 165 mm`s/sec and 45 mm`s/sec^2 the other two kind of work at 2000 steps per revolution 30 mm`s/sec and 0.5 mm`s/sec^2 which is absurdly low...

Ok thank you for the heads up. Then what else could cause the motors to whine? One thing i have noticed was that when I brought the machine from somewhere else and plugged it in the motors stopped...

I have a problem with my DIY router. I have done the testing with one stepper with no load. I have a workstation computer with some sort of xeon processor and nvidia quadro graphics card. The machine...

Hey,
I would like to retrofit a router with the mx3660 controller and I don`t know which VFD to choose. I would like it to be cheap and should be able to route aluminum.
Any suggestions from...

Hello,
I bought a used Isel CNC router which came complete with an old computer which should have the necessary software to run the machine. But the software is older than 25 years old and I can´t...

Ok so the black wire isnt connected to any of the pins on any of the two chips. The yellow wire is connected to pin 3 on the bottom chip.

I will check tommorow. And what if it is connected to one of those pins? what can I do then?

The bob (Leadshine mx3660) requires a seperate power supply for the analog output (+10V is an input) to function. 0-10V is the output. When I supply the analog output with 10V the 0-10V output...

So I guess i have to build something like this?
Digital Pots Achieve Voltage-to-Resistance Conversion - Application Note - Maxim
If Im correct this should solve the problem.

Okay so I have to make an analog pot? What would be the additional circuit?

Thank you for your quick response this is very helpful. I will try to get this together and will post it here as soon i get it done.

The wiring is correct the +10V is the red wire the yellow wire is 0-10V and the black is ground. I changed the ground and the wiper and nothing happened. So I changed it back. When I measure the ...

We measured the outputs of the motor control board (fia 112000) and the wiring should be correct. the red wire is conected to the +10V output from the board (fia 112000) and the black wire should be...

I have been retrofitting an old Emco F1 mill. Ewerything is working fine except the spindle speed control. I run Mach3 which controlls the Leadshines Mx3660 controller. I have configured ewerything...

This is my wiring diagram. 236846

I would answer if i had a straight answer. :) I dont know why I just saw a change over switch in there an I thought that must be necessary and replaced it with a relay so I wouldnt have to turn it on...

I dont know I just thought it was a good idea to do that. I thought it was necessary And so it wouldnt do what it does to you.

I have a problem with the output 1#. I wired it to a 10 v dc power supply to power a relay and it worked untill today. It just stopped working and ewerything else seems fine I tried the relay manualy...

You could use the old stepper motor controller and make your own breakout board but I went for the controller because its easier to build.
Here are some new picture of the spindle control. I...

Yes you can define the pins by yourself like the x axis is on pin 2 and the rotation for the x axis is on pin 3. I havent checked which pins are for the ouputs but thats easy I just dont know how to...

This is the speed control board and the power supply from the old emco... I already measured and the output to the pot is 7.9V to be precise. I know I have to plug it into the controllers...

Yes it does. So instead of the manual pot i will plug the controller in but i dont know how to configure it so that it will work... any tips ideas?
