Config Question

OK, I'm back. Printer is awesome BTW. The Question: where can I check the z-offset is saved
So when I start a print the z-offset is a bit low. I make the adjustment live click Save and it gives the nice message to save the config when the print is done. Print Finishes I click Save Config, it does its thing, restarts etc. Next Print.... Same thing. I have to raise the z-offset to keep the nozzle from scraping the other layers... Because, after the prob calibration it saves that information to to the printer.cfg which includes a calculated z-offset from what I understand. #fix-my-printer...

LDO Input Shaper Toolkit Reports Invalid adxl345 id (got ff vs e5)

Having issues getting the LDO version setup with my V Minion. Just used the same toolkit on my Voron V0.1 and it work just fine. I uncommented [include config/boards/rpi/config.cfg] and include config/printers/v-minion/input-shaper-single.cfg] in printer.cfg. Currently running the updated version of RatOS 2 Alpha so I know there could be a related bug. Any thoughts?...

One Z Stepper changed direction

Hi all - I'm not quite sure where to start with this one! one of my Z steppers has just started to run in reverse. This seemed to happen mid print last night, but is now affecting homing - 2 motors will move the bed down as expected, but the 3rd (front left ) is now raising it. The machine has done many hours of successful prints to this point, and of course no wiring or configuration has been changed. Can anyone think why one of the Z steppers would "randomly" change direction? This is of cours...

Best way to route filament with Enclosure 2.0?

Over the holidays I finally got around to building the Enclosure 2.0 for my VC400. I made my own panels and mounted them knowing I still had a lot of design work on figuring out the routing of the filament and the mounting of my Klipper display. I did not like the Ratrig method of routing the filament thru the back. I figured the inside mounting worked with Enclosure 1.0, so why not that....

V-core3 overheats after homing in 2 minutes and shuts down

Hey everyone. I just finished my V-core3 and yeah the above mentioned problem occurs(see Screnshot attached for the fault). I noticed, that the drivers were getting really really hot quickly just when the printer is homed and sitting there, no active movement. I swapped the three z-axis drivers for the ones I had in my v-minion and the problem was fixed. The drivers are both 2209s but the ones that shipped with the vcore3 where v1.3 while the ones from the v-minion where v1.2(see pictures). Does anyone know what is causing the problem here? Sense resistor is the same on both and they are both 2209 drivers from BTT. Thanks a lot for your input!...

4028 Fan

Cold printer rams bed into nozzle due to leftover ooze

I've had this happen several times now and I am wondering if the correct solution is to just heat the nozzle prior to zeroing the axis or if I just need to move my BLTouch further down. My current Z-offset is 0.47. Is that too little?

(SOLVED) SKR 2 Fan2 incorrect socket?

Hiya all, building my v-Minion from a full kit via Fabreeko. Ran across an odd issue. My SKR 2 board Fan2 socket (which is used for the electronics enclosure fan) seems to be switched around. Board pin out says 1st pin is VBB (+) and 2nd is PB5 (-). Wiring diagram shows fan should be plugged in with pin 1 - red wire, pin 2 - black wire. ...

Bed not heating

Hello all, best wishes! Setting up my V-Core 3.1 400 here with an Octopus 1.1, all going fine so far except for one thing. The bed is not heating up when I try to do so in RatOS. Wiring seems fine, SSR LED lights up red when I ask it to heat, but the actual bed is not getting hotter. Am I missing something? Pretty much stock printer config with RatOS 2 Alpha 4....

Sensorless homing with tmc5160 and SKR 1.4T

Does anyone know how I have to setup sensorless homing with tmc5160 and an skr 1.4T? If I home the axis it just moves endless( even with driver_SGT: -64), if I reverse the diag1_pin the endstops are perma triggered, also tried with and without pullup (^). Here's the cfg. I've read somewhere that you need to cut the clk pin [stepper_x] step_pin: P2.2 dir_pin: !P2.6...

Help - Stepper Issues

Finally got around to building my V-Core 3 with Oldham Z system from BRS. Crazy long build but I believe all square and I think I did IMO, a very good job on wiring. Setup is BTT Octopus 1.1 407 version with 2209 steppers. U2C Can board with EBB42 - this took time but all working great now....
