3040 CNC TB6560 Driver stalling

[Farquarl]

Hello,
im sure a lot of you guys also have a 3040 CNC.
Mine is the 4th axis / leadscrew / 800w spindle version. The BOB is a TX14175 and the drivers are TB6560. I use Mach3 with a LPT connection and my motor settings are 400steps/revolution, 1500mm/m, 400mm/s.
How easy should it to be stalling the motors? I can´t run the router right now until i build a sound isolating enclosure. But i noticed it is really easy for me to hinder the axis moving by hand. For example the i can stall 4th axis with two fingers. X,Y and Z are really easy to stall by hand too. I have no experience with CNC machines but i can´t imagine that this is enough torque to drive a milling cutter to wood or aluminium.

Sounds like you may have some loose couplers between the motors and the screw.

Sadly not this would be an easy thing to fix. I can stop the motors using the little knob at the rear axle. But if im interpreting your comment right it shouldn´t be that way.

Is the motor current set correctly?
Is the supply voltage too low for your motors? Some motors have high inductance and require a higher supply voltage.
Are you trying to spin the motors too fast? Can you stall the axis with your fingers when you jog at a slow speed?

Can you jog two motors together at the same time at high speed? Could be a PSU issue. Mine shipped with a faulty power supply.

I opened the controllbox today and played with those flip switches on the driverboards. This changed a lot i have a lot more torque and the machine runs faster somehow.
I think i messed with the microstep or decay option. I now have to figure out what switch does what. Either by trail and error or i find the info on the web somewhere.
Thanks for the help

Post a photo of your TB6560 board, I'm sure someone here will recognize it and help you find the manual.

Good idea! My board is the TX14207 and looks like this.

There is a thread right here on CNC Zone:
http://www.cnczone.com/forums/steppe...schematic.html

S1: M1
S2: M2
S3: DCY1
S4: DCY2
S5: TQ1
S6: TQ2
S7: connected to a GAL microcontroller... Not sure yet

M1, M2 control the motor excitation mode (number of windings and phases).
DCY1, DCY2 is decay.
TQ1, TQ2 is torque (that is, motor current).
Check the TB6560 datasheet for more details.

hi can you please tell to me the configuration on mach 3 port and pins for this drivers i olso have controler box with this driver but i cant setup in masch 3 bicouse i have incorect setings of the manual . please help .olredy thanks

some time back to answer another post
I reverse engineered a TX4175 breakout board



the printer port pin signals will be

pin 1 PWM speed control
pin 17 Forward Relay
pin 14 driver enable if used

pin 2 X axis step
pin 3 X axis dir
pin 4 Y axis step
pin 5 Y axis dir
pin 6 Z axis step
pin 7 Z axis dir
pin 8 A axis step
pin 9 A axis dir
