The 3040T CNC Router
It’s a standard 3040T, 3 axis, 200W spindle, 3 nema 23
stepper motors.
After purchasing I’ve noticed the spindle is not going
to be easy to upgrade beyond a 500W due to the mounting going to be a pain in
the arse to change. When I get to that point I will get a friend who is a craftsman
and will do a far better job than myself changing the mounting over.
The motors
These are from dongshundj, but as usual the part
number on the motor is not in the list of motors they sell and the deciphering
of the motor from the serial number is not publish on the site. It might be in mandarin
this is a mute points.
57BYGH041F025BD-18
No. 201711
Not knowing the actual current sink on these is a bit
of a pain as I would like to use a TMC2130 to drive these, but this has a max
current of 1.4A. The TMC2130 is similar to the driver on the smoothier board
and is easy to get as a module (around £6 each). I going to assume the current
is more like 2A, and thus I might use something like a TMC5160, which can drive
larger current.
The Parallel Port
This information is an acuminating of what I’ve found
on the web and the documentation from the user manual supplied. I don’t know if
this is correct, when I get things working up will update this table.

The voltage level are probably going to be 5v except
for the PWM which seem to be 10V.
