UI Robot Drivers on MechMate 3

[uirobot]

Well I decided to jump into the deep-end and try something different. These little UIM24004 drivers that Mr. Tiger advertised caught my eye. Hennie and myself decided to give it a go. Brought in a couple drivers and went through HELL with our Customs and DHL. Ended up waiting 10 day's for delivery and R 1091.00 extra for taxes etc. But that is another story.

These things are SMALL or is it small ?

At the back the motor terminals

Come in a box with screws, heat sink compound and a flange. I asked for all the available flanges to test. In future will use the middle size one. It give some space for the wires to clear the unit when mounted on the heatsink.

The first Gecko removed and the UIM online for testing.

Then when I was happy that it works I drilled and tapped new 3mm holes and mounted them all on the ALU heatsink. Used connecting blocks as the terminals are VERY small and I did not want to modify my existing setup too much.

Ran it of a HP power supply as I am still waiting for my new transformer.

Set up the driver for 1/16 step, did some changes in Mach3 and here is the proof.
