Yes that helps a lot. Thanks very much.

I need to remove the Z axis from my microrouter to fit a completely different spindle motor.
Is there an exploded diagram of the mechanical components of the microrouter available for download anywhere?

Just in case anyone else ever considers doing the same and finds this thread...... I've now completed the "upgrade". I replaced almost all the electronics in the big black box with a new 24V 15A switched mode PSU and a 3 axis stepper drive board that connects to the parallel port. I got them both fr...

No it suddenly appeared on all 3 axis. I've had stalling problems before and it's not like that, although I have gone through the motions of cleaning a lubricating with silicone spray.
I've bitten the bullet and have now ordered parts for the conversion.....

Thanks very much for your helpful reply, but I did the firmware upgrade that you suggest when I first received the machine.

Hi I have an old Microrouter, which when I acquired it from a school was working. Since then, the motor has failed (brushes), then the motor control board. Since this was too expensive to replace, I simply fitted an ordinary hand router with manual speed control. This worked to my satisfaction. Now ...

Thank you both for your replies.
The manuals that you referred me to are the reason that I originally joined this forum, but was sadly unable to find them; until you just pointed them out! So thanks.
I've just ordered my silicone lubricant..........

Thanks for your reply Martin.
I'm new to CNCing; I've only had it for a few short months. Could you please explain in a little more detail exactly what is involved in "remove and clean both nuts" please? Or refer me to a document/website that give more details.
Thanks in anticipation.

Hi I have a second hand Microrouter that was working fine. Now, the X axis has started stalling on the first 8 inches of travel away from the home position when moved at full speed. If I jog at 2000, it stalls. If I jog at 1500 it moves fine. Once I've cleared the first 8 inches or so, I can jog at ...

In case it's useful to any US users, or anyone prepared to wait 15-30 days for delivery, I believe that this(https://www.ereplacementparts.com/brush-p-60335.html) is the correct part.

Hi I've just got a second hand Microrouter, and 4 minutes into my first test job, the spindle motor starting arcing, then stopped. :-( I've taken it apart and although one of the brushes is fine, the other one is at the minimum which would explain the behaviour. So I need a new set of brushes for a ...

I've just purchased a second hand microrouter and am strugling to get it going. I create my 3D designs using FreeCAD; this can export in many formats including STL. I therefore need a piece of software that will take my 3D STL design and turn it into NC codes that VR Milling understands. I am aware ...

I have just acquired a second hand MicroRouter. Thanks to this forum, I have found the quick start guide and the wiring diagram. Is there a more comprehensive user guide available for the microrouter? And if there isn't, can you please advise what sort of cutters I need please? (I should mostly be s...
