Fix Issue with VirtualBox and VM Workstation (Windows Host, Linux Guest)

If VM running slowly when using windows as a host or build keep failing in linux. And the green turtle Icon appears at the bottom of virtualbox then the issue is Hypervisor is running. This is not this doesn't seem to be supported in VirtualBox or Workstation

Open PowerShell in admittatur mode

bcdedit /set hypervisorlaunchtype off

Reboot

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.

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.
