No doubt, skip WinPC-NC upgrade, go for UCCNC

Agreed,
I had the same logic. Jumped using a software stack on linux with open hardware.
I am currently using an arduino with a grbl shield.
Going to validate arduino Mega with Ramps 1.4

I was also thinking about it but went to Mach3 because there was no way to test UCCNC with the machine.

As long you don't buy the license it is only in demo mode and you cannot really see how different things work with your machine (homing, zero of Z or tool length, ...).

All those things are critical to me and therefore I wen to Mach3.

If UCCNC would allow to control machine but have only 300 lines of code (like Mach3) it would be great to test (and not too expensife to buy becuase with controller it's cheaper than WinPC USB which I exchanged for Mach3).

Interesting! I would like to know more how this goes.

I am looking to buy the StepCraft in the USA, it comes with WinPC-NC and USB module.
my question is the USB module really only works only with WinPC? is it really useless?
I am trying to decide if I should ask them to remove it to put credit toward the Parallel-Module which is extra, I need the Parallel-Module for the UC100?

Actually UC100 is doing the same thing than the SC USB module. It is a motion controller. UC100 is connected to the PC via USB and to the CNC machine with a parallel Interface compatible connector.

And YES, the SC USB module is a dongle for WinPC software. It is using some propriatary protocol and you could at best reuse it via reverse engeneering, if at all. So, WinPC software is worthless without the USB module and vice versa.

With a parallel board you can directly connect to a PC which has a LPT port and run LinuxCNC or Mach3 or UCCNC. If you only have USB ports on your PC you additionally need something like the UC100 or an Arduino running GRBL for example. An often used combination here in germany is the Arduino together with EstlCAM.

Big hello From europe 🙂
I have pcnc full usb and it works fine without any problems.
Pcnc full is a fine way to start but the pcnc Starter is only for plotters 😆

Great information, thank you!
I do have a desktop with a Parallel port, so I guess I can start using UCCNC with it right away. but I will need the USB if I want to use my notebook. So is the UC100 just a Parallel to USB convertor or is there something special about the UC100?

Thanks again!

Again, the UC100 is a motion controller. This means that the PC sends the g-code to the controller (USB side) and the motion controller produces the step/direction signals for the stepper-drivers (parallel Port of UC100).

When using a PC with a LPT interface, the motion control is done by LinuxCNC/Mach3/... itself.

Just to point it out clearly, neither of these USB solutions is a pure USB to parallel converter. They really generate the signals on their parallel side with a very exact timing. Pure USB to LPT converters also exist, but they usually have problems to generate the signals with the needed accuracy.

ah ok, makes sense.

Also, I just found out they just got a shipment of UC100 and will be able to ship it with the Stepcraft.
