Hi,
Sorry foe being so long to say thank you all in last post now working. Sorry stiil have problems. I have wired all axis up but Z only go's up I have tried plugs and pin and also looked in Homing and limits no luck.

Broken wire or pin between controller and driver DIR terminal?.
Controlling the stepper DIR simply works by switching the 5v on or off to the drive DIR terminal. So a broken wire is the first place I'd start.

Hi It is a home built and was working great until my Geko 540 gave up. Do I use all six wires fro the motor and Bipolar series??

To back up post #29.
If the motor is a 6 wire the TB6600 won't support unipolar wiring.
In this case wire it as if it were a 4 wire stepper.

Ah!!!!.
I see 8 wires.
Best balance for both speed/torque is parallel. Also lowers your inductance. Twist pairs together and connect as folliws:

A+ RED & BLU
A- YEL & BLK
B+. WHT & BRN
B- ORG & GRN

Then 10-45v power supply in the other 2 terminals (marked 32v & GND I think).
Try that.


I see your motors are 3.2mh inductance in parallel (it's lowest level avail). Not great for trying to get fast rapids on only 36v or less. Fine for general cutting speeds.

Hi All,
Thank you all so much for your help. I don't seam to be getting anywere with what I have, I can get full movement on Y axis using Z port on the settings I was using??
If my breakout board is OK then what drivers should I buy??
I am so upset with all this as when we left UK it was running so well. I dont have the money to buy a new Geko and even if I did I have a deep feeling it would not fix things and I would be where I am now but having spent lots of money.
Thanks again guys you have all been a help.

Without a doubt this one. The stepperonline drive is very good and priced well atm.
https://www.omc-stepperonline.com/di...r-motor-dm556t

It shows in the pdf wiring for a 6 lead motor which means it supports unipolar. I also looked at the pdf of gecko 540 and it also had 6 wire wiring examples.
This is possibly why TB6600 isn't happy, it doesn't support it.
So. DM556T driver and myself I'd try it wired half coil.

The drive is available from stepperonline in the EU and it is also available on Aliexpress.
https://m.aliexpress.com/item/100500...001422484003.0

I more or less get everything from Aliexpress these days.
I've given up with UK. Availability is awful, mostly has the cheap stuff, and also at stupid pricing.


You could get the DM542T but the 556 is better value. Price difference is negligable and your motors look like they are 4.2A which is full on the 542. If your motor heat is low at 4.2 you have nowhere to go with it. The 556 gives you options.

DAFT QUESTION.
Do you have all 6 motor wires connected to TB6600?.
Because, if you look at the pdf's in post 33. All 6 wire configurations show 2 wires are disconnected. Only 4 are used on 4 wire drivers.

Hi,
No I have four, After putting wires together I now have four. I was wrong I do have eight wires on motor.
