Welcome to the SeeMeCNC Community

Haha yeah...and my Max is still in pieces right now being completely rebuilt! I have a thread on that process going and I'll get back to it soon I hope. http://forum.seemecnc.com/viewtopic.php?t=10333 As for the Z height, yes you must manually add height to the Z in firmware, allow negative Z doesn ...

the answer has multiple parts. Firstly, because it's a longer run, the larger gauge reduces inaccuracy, since the temperature is determined by what resistance is sensed, and the larger wire has lower resistance. Secondly, the wiring used for bed power is what the Rambo ships with as a wiring ...

As I'm going through this tear down process I'm noticing that the thermistor wiring for the hot end is SIGNIFICANTLY larger than the therm for the heated bed. What's the reasoning for this? Am I missing something here, because it would be far easier to rout the twisted wires up the tube if the therm ...

Well I tied into the PSU. Gutted all unnecessary wiring. I left one pigtail lead for 5v in case I should ever need it..no clue right now why I would, but hey...forward thinking, right? The 4 black ground wires going to the first pin were twisted together, then the 4 yellow for the second pin. Then ...

Man after looking at prices at Digikey for shielded twisted pair...I'll pass! :shock: I'll stick to just twisting everything and shortening lengths. That's what I would have done if I had built it anyhow. big thing would be make sure to either buy new crimp shells (you'll want Molex LP 4 position ...

I've definitely been so frustrated and angry I've FELT like giving up on it, but in the end I just can't. I may not yet have enough experience or knowledge about delta kinematics required to be a good craftsman in this realm, but overall I consider myself an excellent craftsman in many arenas. I ...

PCB bed/snowflake/plate lifted. There's the mess.

Well here's a couple shots. I tried to get the inside from the sides, but maybe when I get the top plate off I'll get better shots. It's a mess.

Huh, nope I have not perceived that type of behavior enabling/disabling steppers.

Does it look anything like this? In this example I still have to move the skate myself, but in your case the skate could drop by itself as the belt tension is too low.If it looks anything like this it is a much too high motorcurrent on your steppers. In my case that was due to Repetier changing the ...

I am skipping over the last few pieces of advice here, but if I understand correctly the issue is that if you set z0, home and go to z0 it actually does not read z0, correct? I have had this crazy making issue before and I nailed it down to mattercontrol. Since then I turned to repetier host and ...

Sounds frustrating. The two times I've had problems with skipped steps were the following issues: (1) Loose grub screws - you mention tightening the motor screws but not sure if you meant the mounting screws or the pulley (grub) screws - if you haven't done those give it a try, and verify that they ...

If it's such a rat's nest, I would take out the screws that hold the top of the bottom plate on, disconnect everything, then pull the wires such that they hang out of the sides while you re-do the cabling and add tie points. If the endstops are falsely triggered, then it can really mess up your ...

I feel your frustration, I banged my head against mine for the first few weeks after assembly and still spit out profanity at it from time to time :P. I definately was not prepared for the amount of post build learning and troubleshooting required. From reading your post it does look like you have ...

Doming like that is probably just a bad Delta radius setting, unless it's an actual ripple, i.e. if goes low/high/low, in which case it's a mechanical issue. I would suggest using one of the online calculators with a Dial indicator to calibrate, it's a lot easier than messing around with grabbing ...

I agree with the above. It does seem like an endstop issue, either the carriage mounts, or the switches themselves are most likely. There may also be issues with the endstop wiring being too close to the wiring for the power to something or another. (I understand that EE's should know better, and I ...

I see two likely issues, one is the endstops. Mine lost precision from homing too fast and knocking them around. They seemed secure, but i stopped being able to stay calibrated, which led me to replace the mechanical endstop micro switch with plain magnetic hall sensors and magnets glued to the ...

I AM changing it in the LCD panel with the "Calibrate Z Height" option....Scripts run from SD card per every instruction I can find written or chatted or forum. Prints run from exported gcode onto SD card. Doing my best to eliminate the software from the equation. I've had good luck in the past ...

So After that I just checked Z and it is perfect at 0.1mm again. I run this script: ; Rostock Max Tower end-stop calibration script G28 G1 Z0.2 F15000 G4 S5 G1 X-77.94 Y-45 Z0.2 F2000 G4 S5 G1 X0 Y0 Z0.2 G1 X77.94 Y-45 Z0.2 G4 S5 G1 X0 Y0 Z0.2 G1 Y90 Z0.2 G4 S5 G1 X0 Y0 Z0.2 And I can slip a 0.3mm ...

Just sliced with MatterControl/MatterSlice, exported to SD and printed. This is AFTER I JUST calibrated Z, adjusted all three towers until they all matched 0.15mm feeler gauge in the middle and at each tower. I then checked the Z and it was higher than what I had JUST set it at 0.1mm. I even had to ...

Adding pics for the measure of the tower squaring relative to the glass bed currently.

Adding some images to the fray. Ok so here's some pics of very early ABS calibration cubes. Not bad at all I thought. Maybe need to dial in some filament specific settings, but I was happy. http://imgur.com/a/qXWjw Some transparent PLA http://imgur.com/a/JwgKP First T-Glase runs http://imgur.com/a ...

Ok so I'm going to respond to your posts in a bit, but for the moment ... Here's my current MatterControl slicer settings for T-Glase I've been using most recently. I won't say they're good because I can't get a decent print at the moment. They WERE good as I did have several fairly decent ...

Ok so I have this situation. I have searched the forums over and over and over and read and read and read and read. I have implemented better than half the ideas I've read and gotten somewhere? And then nowhere. The short data: Rostock Max V2 w/Repetier 0.91 for Rostock, MatterControl v1.5, Trick ...
