Welcome to the SeeMeCNC Community

After working with SeeMeCNC Support (thank you Steve!) we found that the issue was with a faulty hotend thermistor connection. One of the two thermistor wires feeding into the 8 pin connector only had a couple of conductor strands actually in contact with the conductor in the connector. This was ...

Will check more of the wiring later today, thank you for the suggestion on checking the RAMBO end as well. Something else I have noticed is that at room temp (around 25C) the thermistor is reading 80k ohms this seems a little on the low side wonder if that is the problem? Also I have only noticed ...

I am seeing issues on my Rostock MAX v2 which I upgraded with an HE280 years ago. It worked fine for a while after the HE280 upgrade (once I got a replacement HE280 due to accelerometer problems on the original). It sat idle for a couple of years due to life circumstances changing and me not having ...

Main main concern at this point is that I can calibrate the machine (usually) when it is cold but when everything heats up the clearance between the bed and nozzle is much lower and when I attempt to print the bed is blocking the extrusion.

Life got a little busy for a few days but I just got done testing the accelerometer. After homing the printer and running M261 I got INT PIN: 1, this INT value of 1 seemed to hold for multiple runs of M261 without any other action taking place. I then thumped the cold nozzle lightly and ran M261 ...

I did clear the EEPROM before loading the firmware. The main reason I was concerned about the message during boot is because I also get Accelerometer recv errors occasionally in Matter Control. The G28 command that I ran before attempting G29 did in fact home the printer but I waited about a minute ...

Just tried with a fresh install of the firmware Printer set to 2 Confirmed Z Max was 350. Nothing heated and when I ran the Full Calibration from the LCD Menu (G29 from console did nothing) it crashed at the base of the X Tower on the first probe attempt. I really think there is something wrong with ...

Hi Dale, I did a manual check of the Z Max by driving the hotend down to the platform via the LCD and the 369 height is actually accurate to within a couple of tenths. So I started playing around with the M261 command to see if I could replicate the intermittent accelerometer I2C recv error in ...

Also if I run the calibration from the LCD with the Bed on and heated to 100C it will crash even harder than it did at the center when warm but at the tower bases which are fine when warm.

Ok when running the calibration from the LCD and the printer mostly cool it works fine. If I run it while the printer is heated up it probes fine at the tower bases then bottoms out on the first probe to the bed center multiple times until I shut it off. After running the calibration while semi-cool ...

I added ferrite beads to the I2C lines near the RAMBO and at the top of the wiring whip and my initial attempt at running calibration did not have the same problem as before. I haven't fully tested it yet but this was a promising result. I will update again after I attempt a print or two and after I ...

I didn't have issues with uploading the firmware once I got the correct port selected. I did accidentally send a reset EEPROM to my Bluetooth headphones though. They still seem to work. Still poking at some things and will likely pick up some ferrite beads tomorrow or tonight to try on the I2C lines ...

I recently (last weekend) upgraded my V2 to a V3 with EZR struder, HE 280, and wiring whip. I made a couple of adjustments to the V3 firmware settings after some trial and error. Flip Y-axis, adjust Max Z, etc. To make it line up better with the V2 settings. After the upgrade the calibration from ...

Howdy! I am from Austin, Texas via Mississippi. I built Rosie, My Rostock Max v2 from a kit back in April of 2016. Been having a lot of fun with her including printing low poly pokemon and hiding them around town last summer during the Pokemon Go hype. Anyway I haven't really posted to the forums ...
