Hi all. I started a project a month ago. I tried to immigrate Smoothieware from LPC1768 to ESP32. After a month of recoding and testing , I found it's doable. But I don't have more time to push this project faster. Hopefully one or more of you would like it and can help. The project in Github :by voicevon - Developers
Searched for hours, couldn't find any board pin out 32 GPIO. Maximum one has 16 pins connected to out of board, but must be V+, Gnd,etc. One useful link is here: I am not clearly understand discription of : "Five Wi-Fi networks operating modes: 1.BSS STA 2.Soft BSS AP 3.WIFI direct (SDIO card mode) 4.Ad hoc 5.DirectConfig a key shortcut configuration." Please pay attention of #3, Are they sby voicevon - Developers
Hi all, I read a lot about applying ESP8266 to a 3D printer. So excited. It's really cool of taking over SD concept. I am trying to compare the two solutions: ESP8266 nodemcu FTDI232 + USB cable + USB socket + SD card + SD socket. BOM cost 2$+ 15$+ Upload Speed 1Mby voicevon - Developers
Hi lhartmann ,rklauco I clearly know what you are going to do now. Seems you have a good idea. But, I am afraid the step #5 you mentioned as below: 5 - esp loads gcode from SD, interprets it and generates step/direction and PWM in memory buffers. This is totally rewrite a 3d printer firmware, Again, you need to confirm these are not the barrier of your project 1) How open is the MCU chip (Sorrby voicevon - Developers
Hi lhartmann. I read your article for hours, almost read all related blog, forums, videos, even some source code at github. But I can't see the whole picture. So I assume the system should be like this: 1) Firmware (Should be named Wallacoloo, am I right? )Runs on PI. 2) FIrmware read gcode from USB , or SD-CARD. (Possible from ESP?) 3) Firmware translate gcode to stepper driver signal. But whby voicevon - Developers
Hello Shippo, Heat bed and hot end power are all output with high current, sensors are input of AD converter. If put bed power and temperature sensor together, maybe the AD convert get some noise, and CPU cant read a correct temperature value.by voicevon - Sanguino(lolu)
Thank you mydogjustice 1) I reduced acceleration to [200,200,50,300], but the shift still on Y-axis only. works fine on X-axis. 2) I swapped the wire of motor X and Y, the shift is on the logic Y-axis (mechanic X-axis) only, logic X-axis(mechanic Y-axis) works fine. 3) I swapped the stepper driver board, the shift is on Y-axis. X-axis works fine. 4) I swapped the stepper driver board, at theby voicevon - Printing
I got the same problem. I had read this issue and tried everything I can do. Y Axis is shifting My machine: Mendel-A buy from Lulzbot.com, works fine My machine: Mendel-B. I assembly it myself. Parts are: Stepper driver: A4983 Board: Sanguinololu V1.3A Firmware: Sprinter V1.3.11T one of my checking can proof the problem came from firmware. I exchange the motor wireby voicevon - Printing
