QuoteGITRDUN Almost all CNC machines use mechanical endstops for the axes. Some of these machines cost upwards of $100k and much more. If mechanical works good enough for those its good enough for my $500 printer. If opto was more reliable or more accurate i gaurantee they would be using those instead. Just so you know, cnc equipment use the stop as a reference, they only use the stop so they caby Smallj - General
so basically like the title says i cant get it to work, but i noticed one thing that is very odd to me how come i cant find this in my firmware? #define MOTHERBOARD 33 is this line not in marlin anymore? i keep downloading different releases of marlin and i cant seem to find this in any version i find online i only see this // The following define selects which electronics board you have.by Smallj - Prusa i3 and variants
Did you ever come up with a solution? I'm also notice vibration at low speeds, I think it is related to the microstepping not being fine enough or just cheap drivers.by Smallj - Delta Machines
im trying to figure this out as well, I wish i could help lolby Smallj - Controllers

Very good info guys, thank you for the help this clears up a lot for me! I think I am going to make sure my wires are isolated from any interference and I did notice (I could be crazy) that when I had the usb connected to my computer it didn't twitch as bad. I think I may order a 5v 1a power supple for the arduino itself and see if that helps. I'm guess that that the ramps is powering the arduinoby Smallj - Delta Machines

Go to configuration.h and this is where you change your settings. Make sure you are set to Atmega 2560 and the right com port, then flash your firmware on.

QuoteKoenig QuoteSmallj What is the difference between auto level and auto calibration? How would I get around the limited 5 volt power? Could the limited power cause the servo to twitch. It only twitches when the motor are energized, so I am guessing yes, but I still want to ask The twitching servo is not an uncommon problem when also trying to use a LCD, hence the specific question from me.

Thanks for the help guys. I am running an lcd, but I am not using a heated bed. I have an independent heater. Idk if that would have an effect on the 5 volt power but my assumption is not.

I want to use this firmware but I don't know how to set it up. Do I have to download all the files and put them in a folder? Is there somewhere to download them all zipped together? Sorry for what may be a rookie question, I just don't know what I'm doing exactlyby Smallj - Delta Machines
Well I don't understand why this fixed it but it seems it did, I changed my extruder max speed to 25 from 150. It's printing great now. I guess my feed was all over the place. Idk but my printer is working awesome now. It did seem to act a little weird. Thanks for the replays.by Smallj - Prusa i3 and variants
I first noticed this problem when I was adjusting my raft settings i have since changed them back and it seems to be printing okay now. I think i was overthinking the motor thing, however i think it would be cool to always have power to that motor so it holds position, probably not necessary and a waste of energy though. One questions is should i be able to slide the filament up and down insideby Smallj - Prusa i3 and variants
When I say weak I mean I can move it with my hand. I can slide the filament by hand up and down and the motor just spins. When it is doing a move it is difficult to overpower. I feel like when I am doing a thin layer height the motor isn't actually pushing out material. If I print with a layer height over .15 mm I don't have a problem but when I go under that the motor doesn't seem to rotate andby Smallj - Prusa i3 and variants
The stepper motor seems to be weak. I have adjusted the drive up and down with no change. I also connected a good motor up and didn't see any change. I did notice that I could move the motor by hand very easily unless the motor was moving, Then it was harder to move. It seems like there is no holding power like the other axes on the machine. Is there any way to make this motor energized so the itby Smallj - Prusa i3 and variants
Last night after my post i started to look at EEPROM thinking that may have something to do with it. to be honest i don't know what I'm doing and I just try and read through the code to find the changes i need to make. How would I reload the default values and change them? would i need to do this on the printer itself? is there any ways i can change my firmware in case i have a board go bad?

okay, what am i doing wrong? I also found that the stock numbers for the folgertech kossel made my parts slightly to large, after investigating this i noticed that the printer actually had 189/2.25 for the steps per unit which comes out to 84, however with the 20 tooth pulley it should be 80. I made a change in the firmware and my LCD still reads .084, and also my accel and jerk havent changed. Iby Smallj - Delta Machines
So I'm new to this forum (first post), and I normally try and figure everything out on my own, but I have came across a problem I cant for the life of me figure out. So far I have a prusa I3 and that thing rocks. I have never had any problems, i print only PLA on it, and it just keep going and going. it went so smoothly I decided i wanted to build a kossel.
