Sadly the video doesn’t show the complete system. I’m thinking he’s having each servo raising or lowering as needed it’s own corner of the build plate.
not sure what the 180 degree servo is for though…
Has anyone else played around with the servo pins on the Ramps board?
I ran across this video of someone using them for bed leveling… seemed like an interesting approach that could also be used for even more functions.
It’s off when it’s just plugged in… when you connect to it with Repetier, then it immediately gets power. My plan was to use it to power my little 2.5W Laser (no TTL or PWM), but I have a Sainsmart 4-channel relay board I can probably use and control it through the D4 Servo port… I was planning on using it for the spindle, might as well wi…[Read more]
Sorry for the delay, life keeps you busy sometimes…
Oddly, I’m not even getting to feed rates on anything. I can’t even drop the Z down to the work surface without either turning the pineapple for 5 minutes or clicking down 10, then emergency stop, down 10, emergency stop, etc…
I’m still setting up for a print !!!
Everything was running…[Read more]
I recently upgraded Repetier to 2.0.2 and started immediately having Z axis issues. Either it refuses to move under manual, or it randomly decides to go UP when when you click DOWN… if you do an “emergency stop” then let it reconnect, it’ll execute one more command correctly and then stop responding as well. X & Y work fine… I tinkered wit…[Read more]
I print on glass, and it’s “even enough” for my needs… so if I have three points level I’m good to go. I am actually using the MPCNC, but this seemed more printing related than the MPCNC area.
Leveling isn’t a regular task for me, but seems like an area many people are focusing on. Also, I like to reduce the weight and complexity of the…[Read more]
Call me crazy, but wouldn’t it be easier to put simple microswitches on the corners of the build plate and have the nozzle click them one by one to do the autloevel/tramming? Seems like everyone is trying to figure out the best way to mount a sensor on the carriage next to the hotend. Wouldn’t it work better to mount switches on the build plate…[Read more]
You’re right, perhaps better stated “The needle never moved when connected”, so it’s an “open”.
I checked the wires going into the heater cartridge and they appear ok, but still no love… (or heat). I picked up a new one at the local electronics store, will give it a shot.
Thanks for the clarification, I’m an clearly not an electrical…[Read more]
I may have found the problem… I checked resistance to the hotend heater and got nothing… ZERO ohms… so that seems to indicate an open circuit… I pulled the heater element and applied 12v directly to it and nothing… so I’ll try to find another heater element and see if let y’all know if that fixes the problem.
I’m also getting 12v @…[Read more]
Kind of a newbie here, but I think I might’ve fried my MOSFETs. my XY&Z steppers all work fine, but the first attempt at a print started off ok, the hotend began heating, but the fan wasn’t running. I assumed it wouldn’t start until it reached a certain temp, but then the hotend temp suddenly started dropping… all the way back to 22 degrees…[Read more]

as a “newbie”, it took me awhile to figure out what plugs into what… these two files helped me considerably.
