Copy your license file back into the Mach3 folder, as Mach3 licenses are not legally transferable if you didn't buy a license you don't have one -

hi. I have a same bob but linked with UC300. I 'm very interest about your electronic system, could you post a diagram wiring with the list components?
I encounter a lot of difficulties to begin a wiring

Hi guys,

I have bought the same beast and I am considering upgrading it, because the original Isel board requires using Isel code and is absolutely not efficient for 3D machining.

I plan using UCCNC and a UC300 motion controller, as cnc.miller.

I didn't found the stepper motors documentation and I'd like to avoid disassembling the machine to get their model.

Does someone have this information?

Steve, how did you choose you drivers?

Thanks in advance

Hello,

I just noticed this:

So I guess it answers my question…

was just looking for that, drivers, were just what people seemed to like, I bought them from china less than half price of uk supplier,
if i can help in any way please ask

Steve

here is a link to the only data sheet I can find http://www.cnczone.com/forums/attach...6/83328.attach

Thanks for the link, Steve.

I previously found a MS 135 HT-2 data sheet on Isel website, but their current was lower.

So I'll probably go with your drivers or an equivalent, as you seem happy with them.

Hi cnc.miller,

See if Gerry's explanations in this thread are of any help:

Ok, as I'm too lazy to have a look at my machine which is not very accessible for the moment, I'll ask another question.

Do you still have the original Isel IMC4 controller at your fingertips? Could you please check if the driver chips (IIRC correctly, they are located at the top of the card, screwed to the case) are L292?

If this is the case, it means that a 2.5A current is sufficient and I'll probably buy smaller and cheaper drivers.

Thanks in advance.

I eventually managed to open the back cover. Drivers are L292, limited to 2.5A.

I found the electrical diagram of the IMC4 controller here:

For those who want to upgrade the machine without changing the whole electronic part, this upgrade card may be interesting (requires Kay control software):
