Topic: Successful Heatbed Replacement

Hello,

So after my glass bed chipped I decided to look for a replacement. The 214x214mm MK2B heatbeds are widely available on eBay for less than $10. Got myself one and figured out quickly that it is only a few mm too large for the DV print bed. After initially considering shaving a few mm of the circuit board, I instead simply mounted the new heat bed on top of the bed frame and placed the glass on top of that. The metal clips work perfectly for holding everything in place - but I now want to get a 214x214mm glass sheet to cover the entire top area of the heatbed, plus I am considering relocating the thermister to the center. After a quick adjustment of the Z home point to -3 mm and a calibration the printer seems to work just as good as before.

Re: Successful Heatbed Replacement

I would like to know exactly what print bed you bought.  Can you post a link to the seller?

Re: Successful Heatbed Replacement

Great!! Thank you!

A couple questions. Did you use the OEM thermsistor or did you put one in the middle of the heatbed like other RepRaps do? How did you offset the bed -3mm? Was it with some other software (slic3r?)?

Thanks so much! My chipped bed is going to be switched ASAP!

Are you sure that includes the glass? It looks like just the heating pcb to me. Usually the glass alone runs this price.

I assume he got glass from a local hardware store (Ace / Lowe's / Home Depot).

In his original post he only mentioned ordering the PCB heater online.

I think you would be safer using borosilicate glass. Just plain glass is what is used now and I think that is the issue. Maybe thicker like 3mm or so might work. But if I am going to go through the trouble then I will use borosilicate glass to make sure it wont chip/break again.

If you plan to go PLA only you can also use 1/8" anodized aluminum in place of glass. I am not sure if ABS would stick to the bare aluminum like PLA will but you could use painters tape on it as well for ABS.

Re: Successful Heatbed Replacement

Could a second piece of glass be added to original bed, just to make it easy to replace if it gets cracked or damaged?
