Will printing with a raft help against a uneven bed? My bed has a weird area that is higher that the rest and is causing failed prints. If not, is there anyway to help counter it?
Thanks
A raft can help but the bottom of your print won’t be good quality.
Might be a way to compensate for the high point. Where on the bed is the high section? What’s the configuration of your bed?
Use Marlin Firmware with Bilinear Bed Leveling
@Panayiotis_Savva It’s possible to enable that for every marlin version? (I’ve a custom version by my printer manufacturer)
No, it may not be. However you can always pickup the latest version and use that instead. I suggest checking with your vendor if their version supports Bilinear Bed Leveling.
@Panayiotis_Savva thanks! I’m having a issue with the back side of my bed (prints not sticking at all) I think that the carriage it’s really bended.
I would rather fix the mechanical issue if I were you
@Panayiotis_Savva but how? My vendor doesn’t provide that part to buy
Send a photo of what is wrong in this community. Maybe you’ll get some good suggestions of how to fix or where to get the part
@Panayiotis_Savva Thanks, will do. I’m not at home right now.
@Jeff_Parish the high section of the bed is in the top left corner. It has a steady slop, so the printer head just slowly hits the bed until it jams/fails.
Disagree with some of the above. If the warp is insane, then no. If not, then yes it should correct it as long as you have enough layers to the raft. I had a bed that was horribly warped and a raft helped a decent amount.
@Griffin_Paquette the warp is very slight. If i have a good first layer in one area, when it goes to that area the hotend will be too close to the bed and smear. Ill give u a pic of wat i mean.
Ok just a fyi, this isnt my picture. But this is what my first layer looks like when it hits the high area of my bed, just worse.

If the print is small enough it will correct in the next few layers, but when I attempt a large print it fails.
@Matthew_Del_Rosso If is is just one corner and only slight there is a good chance that the bed might be flat and is just out of plane with the X or Y rods. In that case a raft will help but it would be nice to get the printer mechanically precise and avoid that direction. I never use rafts.
Can you check with a level to see if your bed is flat? I use a level and a piece of paper along the edge to determine if the bed itself is flat.
If the bed is flat and precisely leveled and you still get the problem then I’d check to see if you have bent rods.
If the bed does have a warp on the left back corner (paper slips under the level edge) you can either turn the bed plate over (make it a low spot - might not stick but it won’t jam) or try to thermally compensate for the bow by tightening the PCB bolts on the high corner and the center and leave the other three just barely snugged. Upon heating up it will expand faster than the PCB and should bow down flattening it out.
