Hi, I would like to use the openbuild control software 1.0.370 with my pico, I really like the interface. (At this stage, I am only using a bare pi pico - so this could be a problem). I have used the grblHAL Web Builder to generate the pico file but even using the various compatibity modes, the control software can't open the port. The Pico does appears to have grblHAL loaded as I can open the port in Termite and list grbl commands. The updates on the control software v1.0.368 does point to the fact that it should work. Any ideas ?
I tried this out, used the web builder to build for the pico using the -BOB-G540 option and got bCNC to connect. it does come up in ALARM mode , probably because I have no switches connected to the pico at all and it is expecting NormallyClosed limits,. After a rest I can communicate with the pico on the console. However, CONTROL fails to find any device at all, which is weird, it should surely be able to talk to grblHAL installed on any of the supported 32bit hardware?
Does it enumerate as a USB Serial device? We find devices using SerialPort.list serialport | Node SerialPort
David, I have an ESP32 Huzzah32 board. Is it possible for it to control 4 stepper motors, three limit switches, and Z=probe?
I have ordered a PicoCNC board so this should have the correct alarm/run signals connected. I tried another firmware build with comparability set to 10, still won't connect to CONTROL. I will try bCNC.
Use the Web Builder to check which boards allows for 4 axes and a probe input. Be sure to check if USE_I2S_OUT is defined in the board map (this can be opened from the Web Builder by clicking the Board map button) as these uses shift registers for many signals and are not as easy to wire up.
Hi, I’ve built the code for the picobob which doesn’t use shift registers and loaded this onto a bare pico on a development board once I cleared the Estop this worked with the iocontrol software from grblhal AND very briefly worked with the control software, then the control software complained that it couldn’t find a comms port. So near ! I’ve laid out a PCB which is similar to the picoBob with level changers so i will report back when i have this board and if it works.
