Dear Jenna, I have been busy at other things for the fast week, but I just spotted your reply. Using your suggestions, and the Makecode blocks, I actually managed to finally get it working. It needs a little fine tuning, but it works. I can't thank you enough for your determination and assistance. I really appreciate your help. Thank you. ;)

Jenna, thanks for the reply.I should have mentioned that the stepper motor that I want to control, requires a 24V supply. That's why I need to use the TB6600 microstep driver. That DFR0548 motor controller, appears to have a max supply voltage of 5.5v DC, so I doubt that it would suit my application. The Graphical block software library that you directed me to on GitHub, would be very handy if one was using that controller board. If only there was something similar that I could use for the TB6600 driver board that I have. Any suggestions welcome.
