Are Nema23 stepper motors defective?
Hello everyone, I'm currently building a gantry milling machine. For this, I purchased three nema 34 stepper motors and a TB6560-based oyostepper controller. Now that I've connected all three motors, I've noticed some strange behavior with one of them: When starting slowly, it jumps back and forth before running normally.… -
P2XCForth - A Fast Hybrid: XBYTE and C
Hi, once again an experiment to create a Forth für P2. While P2CCForth worked and brought together the Forth world to the innovations of the Obex, it is slow in comparison to Taqoz. So the question was, if the special XBYTE mechanism of P2 could be used to go the other direction and make a Forth for P2, which is even… -
towards a P2 Virtual Machine using XBYTE and Subsystems
This is some experiment exploring possibilities of P2. Overall goal is a self contained system like Taqoz with SD card using PC with Teraterm as terminal. One aspect is about the virtual machine: I asked myself, what would be the most "natural way" to implement a dual stack machine (Yes, my implementation shall run Forth,… -
Re: P2 Floppy Drive Controller
Yes, it also meant that the amiga could read all different floppy formats independantly of the controller chips used in other computers. The best copy protection I heard of was writing a "wide track" with an old 40-track drive. You can read it with a 80-track drive while stepping the head position motor forth and back… -
Pondering about another Forth for P2
So while I do appreciate Taqoz, because it is optimized for P2, fast, compact and complete, I nevertheless ponder and wonder, if there could be an alternate way. Motivations 1. It would be nice, if we could use drivers, others have written and placed in OBEX, so an integration into FlexProp together with SPIN or C files… -
Question about Pointer Behaviour
Background: For my knitting machine, I want to add a camera as sensor. The camera is ESP32 (Tensilica) based and I use the Arduino environment for this. Which uses the GnuC++, as far as I know. Unfortunately I updated board definitions for ESP32 and since some code does not work anymore as before. The routine is part of a…
