Welcome to the SeeMeCNC Community

Haha ill be sure to share the victories when they come, but it looks like today is still not the day. something is still screwy with my PRINTER_RADIUS. the nozzle sits a touch further above the center of the bed than it should. it seems like changing the PRINTER_RADIUS value isn't affecting the ...

Yup, i feel smart. it was in fact the printer bed settings. about to try for my first print, woohoo

Well it turned out that the chokes didn't help at all, it was in fact a grounding issue causing the gremlins. at this point i should be ready for my first print but slice3r is generating some funky gcode. i mean the test cube looks right and everything but it is trying to print it centered on the ...

Well it's only a few bucks for a cheap pack of chokes from the regular places so i'm not really out anything if they don't work. however i've never had to incorporate them into a build before so i don't know if there is some particular size or something i should be looking for.

I have tried isolating the endstop/stepper wires from one another as best I can in the limited confines of the electronics bay with no apparent change in behaviour. I'm tempted to try throwing ferrite donuts on the endstop wires just to see if it makes any difference. Thoughts on this?

I have spare time today so I will go ahead and humor you all by checking on these wiring suggestions. but I would like to point out yet again that the towers behaved EXACTLY as they should up until the moment that a firmware change was made. there were NO hardware changes made at all. Unless ...

Sorry about taking so long to get this second upload up. I didn't realize until long after I posted the link here that it was the wrong video. But now hopefully this will shed some light on the situation.

haha yeah the music. the printer was dancing or something. As for the misbehavior being tied to incorrectly wired steppers, well ill just say read my first post and ill leave it at that.

sorry about sound/video quality, this was shot in a rush on my way out the door for work the ohter day. just now getting time to post links

i wasn't aware that you could control the printer directly from the LCD. i will be trying this and editing this post within the hour Edit: it turns out that when attempting to home the towers from the LCD i get the same jitteryness as before. this may just be wishful thinking but they did seem to be ...

that actually makes sense but im not sure how bad accel values would have persisted through multiple attempts to wipe the eeprom/flash stock firmware/ etc

yeah thats the thing. it is all 3 motors behaving strangely and all three motors were acting very smooth with no issues at all until the first time i tried to move them after setting that ignore eeprom value in the firmware and flashing it. from that point on this has been an issue. a firmware ...

i wont rule out the possibility but i find it highly improbable because as i said i checked the wiring about 10e53475734 times. also the way that the motors are moving doesn't seem like a short/open issue to me. i will shoot a quick video of the printers behavior later on tonight to hopefully better ...

*Continues staring intently into the monitor chanting* hear my cry great oracles, bestow upon me the guidance i desire.
seriously though, anything else i can try since the eeprom clear didn't seem to help at all

well i got my hands on a usb cable this morning and tried wiping the eeprom and then flashing the stock firmware from the github but there didnt seem to be any change in behaviour, any other ideas?

well, it turns out that somewhere during the intervening months since i last attacked this project the usb cable has vanished from my work area. I will see about getting a new one today and update this thread later tonight or in the morning. thanks for the help so far though!

that is something i hadnt considered, let me give it a try

Oh great citizens of the internet, I humbly throw myself upon your mercy. me/my roommate picked up a Rostock Max several months ago, back when the bad Rambo boot loaders were going around. we sent in our rambo and got it flashed and then continued with the build process as normal, everything seemed ...

Haha, sorry for the late reply, but I've been busy with a new job and all that jazz. When Geneb and Maybe-Geneb get done beheading each other, could the victor maybe hit me up? I still need to get this printer figured out. It has been making a great door stop for months now and IRC still says Geneb ...

Haha yeah, that is rather strange. Well thanks for looking into it anyways.

If you do figure out what the heck was going on, please do fill me in k? Would be nice to know what broke

Well rather than hijacking this thread ill just shoot you a PM if thats kool with you.

Oh wow, I had disregarded your name until the second time I read your reply haha. Someone on the RepRap IRC @freenode suggested that I get a hold of you because of some issues I was having with my Rostock Max. Well, that is assuming you're the same Geneb they were referring to.

My old username was just "Neorpheus". I'd hate for someone else to get caught up in that same situation and get discouraged from taking part in the forums. I'm in Rochester, no clue how far that is from you though as I really don't know my way around yet.

Yeah sure thing, I won't go cluttering up the Introductions section with trouble shooting junk though. I will be rolling a detailed post in the troubleshooting subforum when I have time to gather some info (likely tomorrow morning)
