Bed Insulator, Nozzle Mount replaced with Metal Parts. Hello All Well I have been having loads of issues with the "Bed Plane Compensation" where I am having to do it before every print due to any slight movement like even removing the last printed item or even cleaning the bed after the print changes the previous setting. So I have opted for a 3mm aluminium sheet 500mm x 300mm (so it will need to be cut to size and use the bed-insulator as a template) along with a 19.05mm x 19.05mm square rod to be cut to replace the "nozzle-mount" will also need a few holes drilled then cut and filed to size. Along with loads of 20mm M3 Socket head cap screws, washers, locking washers and hex nuts. Hopefully with the above changes (if all goes well) I should have a level aligned bed and a nozzle mount that doesn't melt or soften resulting in sagging after long prints. The above items etc should arrive over the next couple of days, so if all goes well I will post some pictures of the changed items. Ian, I will try and return the faulty Duet board some time next week, I will also email you the Tracking code and don't worry about refunding the return costs, shouldn't be that much anyway.

.....The real problem is that the back bearings are some distance from the back corner bed support points, and the MDF isn't stiff and stable enough, so it tends to sag in the back corners.....

It don't have to be that way, turn the bearings mounts 180 degrees and put the rip on the other side - and the activator for the micro switch, print it as a part of the bearing mount, it so logic that I wonder why it was not made that way in the first place

Edit: but then again, I also wonder why the made the bed of fluffy stuff like MDF

You can get rod of exactly 16mm x 12mm but you need to be exact when slicing the 4 sides off.

LoL I was extruding yesterday when it was quite choppy out there.
I don't think I could have left it printing without the cable ties.

I'm not sure what sort of service they offer via post, but you can sound them out.

I used an offcut of some 45mm plate I bought from them recently, I'm not sure that you can get delrin (acetal homopolymer) or acetal copolymer (aka POM ) in anything other than round rod, sheet and plate easily. I said Delrin, but actually I used acetal copolymer - not much difference between the two in this context though. of course if you have a mill, you can square up round rod pretty quickly (it's lovely stuff to machine, just don't do it too fast to keep the fumes down).

If you can't find anything at a reasonable price, I can send you a chunk big enough for the bracket if you like, pm me with your details,

Cheers

What I intend to do with the table:-
As for the table I like the idea of two more ribs, as close to the ends of the carriage longitudinal as poss, with one or two longitudinal stringers to stiffen it all up. Then to make it even better, move the existing bearing to one of the new ribs, and buy another bearing for the other new rib, so by making a raft on 4 bearings. Well that's the way I want to go.

I do wonder if you can print on to ally sheet, and think it would be ideal for the IR Probe.

(Ian if your reading this, I did message you about some parts I wanted to buy on Wednesday when I pass by to go home.
I think you might have lost the msg as I haven't heard anything).

I replaced my nozzle mount with delrin (stays stiff up to 175 or so)

Ray
Can you tell me where I can obtain a piece of delrin, checked on eBay and all I can find is round bar, presumably it is also supplied in square section.

Well I had seen that a few other people had changed their nozzle mount so I thought I would do the same, I was buying 19mm x 19mm square aluminium rod for something else and thought may as well use 40mm of that rod for this.
I will still be using the MDF insulator between the two metal parts and I am hoping that with an extra bit of heat compound on it will also transfer the heat if any also over to the heat sink.

As for the Heat Bed, yeah I will still be using the cardboard sheet plus there will be a few extra mm gap for the alignment of the bed.

Didn't think about the bearings.

Thanks
