Quotebuffcleb Quoteflatlander Quotebuffcleb So I installed TMC2100's on the X&Y axis. If I lower the voltage below 1.15 I get a high pitch squeal from the Steppers... at this voltage the steppers run pretty hot... reading online I saw that running the TMV2100 off of 18 volts or higher could eliminate this.

fixed... I removed the diode from the ramps that supplies 12v to the Arduino and am powering the Arduino from the usb... first tests show everything works... can get x,y,z to go and read files from the SD card again... the power strip I use has USB out so for now I'm good to go... I have a replacement arduino on the way but I'll order replacement AMS1117 5.0 regulators as well so I have this oneby buffcleb - RAMPS Electronics
so using this image : going from pin 1 to 2 I get 7.81v going from pin 1 to 3 I get 11.25v I'm using the Arduino removed from the printer without the ramps attached running on a 12v power supply that fits and is normally used for external hard drives. Directly checking the output of the cable shows 12.6v so I am assuming I should get 5v from 1 to 2... should I get 12.6 going from 1 to 3 orby buffcleb - RAMPS Electronics
looking online maybe the 5v voltage regulator is fried : going to check the board... I do know that that end of the arudino was warm when I removed the board.... I have a 7805 in my misc parts box... so maybe? does it sound plausible that that could be the issue... I have built lots of electronics projects but tend to follow the instructions not design circuits...by buffcleb - RAMPS Electronics
was getting ready to install a bltouch and added the 5v jumper. I wanted to test it with a multimeter and opps it shorted them out and it rebooted... it powers up, slower then it did beforecan't control any of the steppers (choosing move on the LCD does nothing - ( tried moving X, Y and Z )can read the temps (displayed on the LCD screen)can't read the SD card if I plug the card in the display flby buffcleb - RAMPS Electronics
QuoteBert3D Quotebuffcleb I got my BLTouch a couple of days ago... Printed up the mount and went to mount it but I was pretty sure there was supposed to be an adjuster in the middle hole... right? The adjuster is there. You poke a 2mm hex key down in the center hole, and it should turn. I recommend printing the mount 2 or 3 times taller (scale z by 200 or 300 percent) so it sits higher. Thatby buffcleb - Prusa i3 and variants
