eBay TB6560 Stepper Motor Driver Boards

[1113562]

Another Newbie,

I am looking at using this board as a hotwire cutter for RC aircraft wings (4 Axis).

1. Does this board need any other driver boards ? (i.e. Direct connect computer to printer port, stepper motors direct connect).

The driver board needs no other parts other than a DC Power Supply. Mine came with a Parallel port cable to connect to the PC printer port and came with the connectors for the stepper motors which allow you to connect directly (they have screw terminals in the connectors - quite neat). The DC Power supply to drive the board and steppers needs to be of the correct voltage and current rating. I have a FARNELL B30/10 PSU which is variable 0-30V with a current output of 10 Amps max continuous ..... ideal for this board. If you have to wire in HOME/Estop and End Stop safety switches you will need to seperately purchase a small header socket and crimps to fit the tiny 2 mm pitch PCB header for these interfaces. These are available from RS - I can advise part numbers assuming it is the same as my board.

2. Is there an updated manual with correct pinouts as you guys have discovered ?

The board I have is a 3 Axis plus spindle start/stop relay but I believe there is a 4 axis version. The manual for the 4 axis may be correct for pin-out and DIP switch settings.

As you may have read, the silk screen notation on the printed circuit board is correct so if your manual that comes with the board does not line up with the PCB artwork then you should ask questions (on this forum perhaps) before you connect and power up.

I've received my TB6560 and started bench testing for a 4 axis hotwire configuration. Looking at using Mach3 + Profili2 for the G-code.
I'm using Axis X, Y, Z, A, running Mach3 v3.042.
Problem is that two of the axis are really slow. I have swapped around the motors to prove there OK. So the problem is likely Mach3 config.
Mach3 was more complex than I expected, so far can't find the configuration problem (I''m an electronics Tech).

Anyone offer any advice or a config file to help out.

thanks
Rick

Rick,

Define 'slow' .. do you mean they dont rotate at the same speed as the other channels with the same settings? I assume you've been through the 'motor tuning' process in the Mach3 tutorial?

I have included the TB6560 Mach3 configuration file that came with my 4 axis board.

Purely bench testing at the moment, board and motors only on the bench.
While in Mach3, when I tab to get the manual controls, 2 axis are at least 100 times slower than the other channels. All the Mach3 motor tuning is set the same.

My board came from a seller that does a video of your board (as waranty proof) before he sends it out. I got the steppers from him also. It showed all 4 of my stepper motors on my board operating at the same revs.
One of his other videos walks me through basic setup, which I have followed. But essentially the config file loads up and I should be good to go, at least for bench testing motor spin.

He did mention, often DB25 cable configuration is a problem. I measured it out, all good, pin 1 to pin 1 etc, is correct. He also mentioned computer bios, will try and get time tonight to have a look. But as I can get 2 channels to operate fine, even when I swap motors around, I don't believe it to be a PC bios problem.

Still a confused newbie, sorry to be a pain guys.

I've just loaded your attached profile.
All the velocity / steps / acceleration settings are the same so I can't really see what might be causing it.

Are the slow motors missing steps? Try sending a slow motor one turn forwards then one back and check it returns to the same point. It might be that the driver board is 'missing' lots of the pulses making the motors go slow.

Try going to config->motor tuning and putting the velocity setting up for the slow motors and see if it makes a difference.
