@@fuzzy4logic THank you. It works great, except the boot loop when 12v is pluged in before usb. Otherwise it works now great. I also added the 10k resistor between EN and GND like shown in you video. Any ideas to this?
BTW The ESPduino power connector handles up to 18 volts, in theory you could use the same power for the ESPduino and CNC motors. I was wondering if you tried this and what was your experience with it
I've tried it with 12 volts but the regulator got pretty hot. Because it is just a linear regulator, the remaining power gets turned into heat. I use mainly buck/burst converters now
Hello mate, I have an issue with the ESPduino while using the CNC shield on top of it. I used to connect the uC with UGS normally with the CNC shield on top of the ESPduino with no problem, but now there's something strange. I can't connect it with shield on top, just without it and then adding it on top. Do you know what's the issue or where to start looking at? I'm currently using TB6600 drivers, CNC shield (same version as you), and ESPduino Wemos D1 R32 I made connection with a regular ESP32 with no issues and monday morning I'm gonna make a test with a CNC shield based for Arduino Nano using a ESP32 Nano instead. Hope you're doing it ok, I enjoy the quality of the info you give. Hoping for an answers, greetings from Perú. Sorry for my bad english btw
This sounds like a pullup/pulldown issue. Check the boot output over serial to see if it is stuck. Some pins configure the flash voltage of the esp during boot and having pullups/pulldowns can really mess things up. You can remove the resistor on the cnc shield to see if it improves things. No bad english in sight ;)
i've been trying for several days to get the esp32 with a pin breakout board to work with stepper drivers (dm542t).. which i have succeeded once.. but now nothing seems to be working... i don't have the proper electronic testing equipment like you seem to have.. but the enable pin (gpio.17) does work when doing $me or $md.. but when sending a signal .. no dice. any chance you have an idea of what could be going on? and also you on any discord server or?
Of course I like this video and I'm even going to subscribe to the channel. I'm dreaming of building myself a precise Pen plotter, and I'm sure all this information will be invaluable to my project.
Thank you for the video. I was wondering if there was a way to get a copy of your config file? Since all of this is new to me it would be helpful to have an example to work with.👍
I made a discovery. When downloading his config file. Click on the link and download using the download "button" if you download the first link its going to be HTML code inside of the config.yaml file. That threw me for a loop getting config file issues until I opened it in a TXT editor and said W.T.F.???
