I am experiencing X layer shifts when attempting to print large objects. (if I print moderate objects there is no problem) I am using Orca slicer, with PETG filament, bed temp=80degC, extruder temp=255degC To give a little context these prints measure 19x12x4.75 inches the print dcrcs\_3d went for 19 hours but suddenly failed due to layer shift at a height of 27.5mm (the layer shift moved to x axis by 7mm) . so I instituted a z hop in Orca, and cooled the X stepper motor via a fan the print tcrcs\_3d went for 24 hours and failed due to layer shift at a height of 27.5mm (the layer shift moved the x axis 5-7mm) . ![tcrcs_3d_closeup](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/d/d750595753162e1f91f87b7e1d10928125d34ea0.jpeg) (I have printed the dcrcs model in another orientation on my Neptune 4 Max printer with no problems…ie it is not a slicer problem) It is extremely frustrating as I bought the Comgrow T500 because it boasted a 500mm3 print volume. Is the any fix for this problem? ---

Since it happened twice at 27.5mm, check your Z-Rods around that point for a flat spot or maybe a bind. Also, a full pic of the model would help… My guess is it’s a speed issue & the model might be thinner where this is happening. ---

That helps with the over view. I guess I wasn’t clear, you said you printed this model before…can you post a pic of the finished model from the top & side. Also, what infill are you using…?? ---

15% infill, 0.8 nozzle, speed 90mm/s I checked the Z rods and didn’t find anything amiss. Before I tried to print tcrcs\_3d in an upright position, but this failed due to 2 layer shifts it happened about 24 hours into the print at heights 88mm and 105mm ![tcrcs_3d_upr](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/0/0c2462edc4df30dd139c458d3d20217575818e2a.jpeg) I printed the dcrcs\_3d on my Elegoo Neptune 4 Max NOT on the Comgrow but with Orca slicer, 0.8 nozzle, 15% infill (identical to what I used on the Comgrow T500) ---

15% Gyroid…?? Hotend temp…?? Filament…?? You don’t have 2 shifts, it looks like 3 to me. ![bbb](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/5/5a7a321b9e755b0d77a255d0478644a6bb6bceba.jpeg) RED: Print issues before the shift. BLUE: looks like the 1st shifts on the left & middle. I still can’t tell the full issue because the are no pics of the completed print. How about a slicer pic…something that tells me what this model is supposed to look like. Maybe a link to the posted model. ---

Are you sure for the filament temperature ? It seems very high ---

The filament manufacturer recommends for petg a hot-end temperature of 230-260degC I have set the first layer to 260 and subsequent layers to 255. ---

I have a question for you is the model too complex (ie. is the file size too large) can the file be loaded in the comgrow memory all at once? Could that be the problem? ---

Honestly, I’ve never print PETG above 235° except for the temperature tower. I’ve made a new one yesterday and found 235° as usual. ---

I haven’t Comgrow T500 so I can’t give you the answer. For such a precise question, ask to Sovol at [info@sovol3d.com](mailto:info@sovol3d.com). Good luck ---

dcrcs\_3d is printed on the Neptune 4 max upright because it the only way to print it (just!) my attempt to print tcrcs\_3d upright on the Comgrow T500 failed because of layer shift so, I tried to print the dcrcs\_3d and the tcrcs\_3d on the Comgrow T500 in the flat orientation (it saves on filament) but once again it fails because of layer shift cannot load the stl or 3mf because they are too big (28MB) …i’m limited to a max file size of 8mb can the file (the gcode) be loaded into the Comgrow T500 all at once…maybe that’s the problem?
