It is stepper setup and motors run very, very good from original contrall. I have started conversion yesterday and can’t get motors turning in whatever I tried.

I think I run through all possible combination of data on Mach3, table moves left and right (I started with X axis first). It doesn’t sound correct whatever I do. I still have old control working and I can hook it back just to compare.

I don’t use Geckodrives, just feed DIR and STEP on original driver board for X axes from corresponding printer port output.

From Dyna 2800 original control motors works beautifully, the movement of every axis is very smooth and dynamic.

It looks like I have to probably buy Geckodrives G201, may be Dyna original driver boards don’t get on well with Mach3 signals from parallel port.

I am retrofitting for first time and can’t get motors turned in whatever I tried.

The machine is Dyna 2800 and I have wiring diagram for it. I don’t use Geckodrives, just feed DIR and STEP on original driver board for X axes from corresponding printer port output.

If you have any suggestions guys, please let me know.

Just spoke to very helpfull technical support at gecko drives and got answers I needed.

Another qestion is about MACH3. When the milling machine homed, steppers are cut off by limit switches, what cuts steppers off when they reach opposite to limit swithches direction?

Thank you,
Do gecko drives completely substitute Dyna built in driver boards or they are inserted in between? Which gecko model can you recommend and where can I buy those in the UK?

New to the forum and retrofitting.
I have Dyna 2800 with control I can’t handle; downloaded demo version of Mach 3 and it looks much friendlier than Dyna original.

Watched few times videos and read as much as I could, but don’t know what is my next step.

I have a wiring diagram for the machine, and for example on X driver board there are contacts DIR and STEP. Do I just connect them to corresponding pins on printer port of the PC or I need to install something in between?

I got dyna 2800 cheaply, would like to retrofit it to use with mach software. Would appreciate advice from anyone who done it with Dina.
Thank you
