After a lot of searching and scouring the net, the problem was related to the STM32 Core Version installed with PlatformIO Although 1.8.0 Is the latest (and was installed) this caused the board to "freeze" for lack of better terms and lose it's USB connection. By disabling the watchdog function, communication was restored but still no temp readings. The interrupts are not working for the temperby Bartje64 - General
I've decided to upgrade my printer electronics from the Rumba (8bit) to the Rumba32. Boards are size / layout wise identical and would make for an easy swap. Using Marlin 2.0 flavor and PlatformI0, the code compiled without any errors and uploaded no issues....and that's where it ended.(FYI software is all the latest versions) When connecting via USB (Repetier Host), the connection would break aby Bartje64 - General
Just some info... For those of you that are using the BLTouch, be prepared to receive "0" response from the manufacturer ANTCLABS. I've been using these on my printers.....last one failed after 7-8 months of use. At ~$40 a crack...that gets expensive. Have written several times to them....no response.. Time for an alternative....by Bartje64 - Reprappers
Hello all, Hope this will fit in this forum. I've had issues with my new BLtouch not performing the self test upon power up.Instead it steadily blinks red but it still will function fine as far as bed leveling goes. Hunting through the forums, I did not find a lot of info, other then check the wiring and it is defective... Then I found info at Antclabs that proved helpful.. Quote.. 2) if the reby Bartje64 - Controllers
Correct, at 250ma it just did nada....(but vibrate).. So I've been playing with this now for some time running the 2130, then back to the 8825, Playing with the current on the 2130..up..down..playing with different speeds but have not yet gotten the 2130 where I wanted it... Ordered a 12-24V dc-dc boost and am going to try that with one axis using the 2130.... For the heck of it, I checked theby Bartje64 - Stepper Motors, Servo Motors, DC Motors
Well I plugged in the motor data (EMF calculator) for what I have currently and what I was looking at. It has me confused.... Current: 84oz Bi_polar, 1.8Deg, 2A, 1.4Ohm Phase resistance... If I'm reading this correctly......and reduce the motor current to 250ma..my torque slips low at 243, high at 260.. Increase it to 850 and it gets worse....low 175, high 223 Both have peak back emf of 8.2v aby Bartje64 - Stepper Motors, Servo Motors, DC Motors
This is currently what I have on each axis. Sticking with 12V supply since that's what I got... 84oz Bi_polar, 1.8Deg, 2A, 1.4Ohm Phase resistance... I'm thinking of going to these for my X and Y 62oz Bi_polar, 1.8Deg, 0.85A , 6.2 Ohm Phase resistance...(42x42x48) Or these.. 85oz Bi_polar, 1.8Deg, 0.64A , 15 Ohm Phase resistance... (42x42x60) What are your thoughts?by Bartje64 - Stepper Motors, Servo Motors, DC Motors
I fell into the same "trap" with the 2130's. Purchased them to make the machine quieter.. Installed on the X and Y axis, configured the firmware and fired it up....holy sh@t I thought the axis were coming apart...jerking and rattling to no end. Re-checked the firmware settings and connections...all ok. Lowered the current settings (from 1000 to 800) and fired it back up. Same result when movingby Bartje64 - Stepper Motors, Servo Motors, DC Motors
Okie doke....thanks for the reply, that answers my question...by Bartje64 - Firmware - Marlin
Hello all, Working on a custom project that will use a 7"tft/Mega combo as a touch screen for my reprap with a Rumba+. The interface between the two systems will (hopefully) be via serial comms. By Marlin default, the board uses Serial 0 for communication, Serial 0 is the usb port on the board. this is fine and works. The board however has an additional Serial port on EXP3 (RX3, TX3 on pins Pby Bartje64 - Firmware - Marlin
