Quotegammasistemi I'm wondering if instead of the rectangular cuts for the current vertical mdf parts, we can't only make screw holes that allow to fix the bed to bearings by using 2 PLA printed parts. In this way we can definitively eliminate all the parts in MDF. Roberto Well it could easily be done, but in my view, the wood parts that are left are vertically mounted which is the strongest aby Davek0974 - Ormerod
Quotecannibalistic_cow Hi, I'm hoping that I'm not too late as you said you'd put the order in on Monday, can you put me down for one as well, pretty please. On an operational side of things, would replacing this part require running through the axis compensation again? Not that its a problem, just currious. Thanks. As in running ormaxis again? If so probably not as the bed should have been pby Davek0974 - Ormerod
Thanks all for the encouraging response, I'll get the order in Monday morning. This will be for a bed with 3mm drilled clearance holes at the mount points, not tapped as suggested earlier. Does any one need some M3x20 cap head screws as well?? These should be long enough to give adjustment and allow for locking nuts underneath.by Davek0974 - Ormerod
Very nice, is there a list of plastic parts needed before fitting?by Davek0974 - Ormerod
I've got a spare roll of grey PLA, keeping it the airing cupboard with the linenby Davek0974 - Ormerod
It would certainly last longer, 3mm thread into 3mm aluminium is ok from an engagement POV but strength wise it's pretty weak. If no other ideas come forward, the holes will all be 3mm clearance drilled by me.by Davek0974 - Ormerod
Quoteormerod168 Quotefrank_bee ...Have you thought to do the corner holes at the guideline size for hand tapping?... I think you will have to put nuts on both sides of the alu anyway, you will need at least two steady bolts to carry the weight of the upper bed Erik Ok, so how about just make them 3mm clearance holes, quicker and easier, not laser cut though, drilled, it's more accurate at thatby Davek0974 - Ormerod
For a small consideration, I could drill and tap the corner holes to 3mm, if that's what everyone wants in the corners I have my own engineering shop in a double garage, but have no laser or water jet of course, just lathes, mills and tools by the ton. Tapping the holes out would not take me too long to do. Would that be a help??? I will look into emakershop as I have not heard of it untilby Davek0974 - Ormerod
Wow, that's some impressive effort Would it then still be an ormerod Nice ideas though, I'll probably settle for a new non-droopy bed mount when I get them made and manually the level bed to the mount then hope to not need compensation.by Davek0974 - Ormerod
If you remove the X belts and runners and place the motor on the gantry, you have pretty much got a standard CNC router/plasma table, just lighter in mass. This is how I got into the 3d game show, I have recently built a small table 600x600 for plasma cutting metal, it was while waiting for the arrival of the cutting torch that I dabbled with extrusion printing on it.

Yes of course, will be placing the order Monday if all is ok.by Davek0974 - Ormerod
I put my auto compensation co-ordinates into config.g as suggested in the manual, using the M557 P1, 2,3 command. I also have different co-ordinates in my setbed.g file for manual stored readings. Upon prepping for print I run setbed.g but thought I would try an automatic run so issued a G32 from pronterface. Instead of moving to the M557 coordinates it went instead to the manual ones and proceby Davek0974 - Ormerod
Of course...by Davek0974 - Ormerod
That was quite interesting, thanks. I have now got the right profiles in and last night I printed the herringbone filament gears which came out exceptionally well, the 0.24mm layer was the issue i think. Possibly an issue with the filament reel jerking the X-axis arm slightly as it unreeled, will check that out too.by Davek0974 - Ormerod
Sounds like we're almost good to go, I have modified the DXF slightly to shift the relative position of the three critical bed mount holes towards the pointy end a little and given more meat around the hole locations, I have also provisioned the three points as 2mm piercings or pilot holes. I will reconfirm if the price has altered slightly and get an order drawn up today for the first batch. Wby Davek0974 - Ormerod
Looking good, we're up to 10 units, I'll wait a little more while looking at the slight mod mentioned above, maybe we can get the price down a bit more. Everyone ok to pay with paypal?by Davek0974 - Ormerod
I have the correct profiles installed now, the screen shows "ormerod 0.5" in pronterface ini boxes now. Got some gears printing, see how it goes.by Davek0974 - Ormerod
So, with the heater connections on the right as you look at it, adjust shape, move the bed slightly right and make pilot holes? Should be ok, doubt three piercings would affect the cost much.by Davek0974 - Ormerod
Looking goodby Davek0974 - Ormerod
Quoteauser I would like to join in but i'm not sure if you are willing to deal with international shipping (to switzerland in my case). I would have no clue how much shipping would be but in total i would be willing to pay up to 40 gbp max (incl. shipping). Of course i can, I send stuff everywhere I would guess it would be easily done for under your limit.by Davek0974 - Ormerod
Ok, how much are we willing to pay? I.e. what quantity do we need to hit before it reaches the price we are happy with?? I will have one of course, and that's two others so far. If we hit 10 I think that's £16.50 a piece plus outward P&P, probably only £3 ea. Please note that I opted for the version without the small holes for the 3 bed screws.

Hmm, possible, will check. I have just noticed that i have two different sets of slic3r settings, both were downloads and one shows the layer as 0.4 / 0.35mm which is what i used at home, the other shows the layer as 0.24 / 0.24mm which I have just found at work on my test bed for slic3r. Can someone point me to exactly which one is the correct / best set of profiles to be using??? One uses hoby Davek0974 - Ormerod
no, slic3r was definitely set for 0.4 / 0.35mm If the axis was slipping, it wouldn't be so precise surely, every 4 layers???by Davek0974 - Ormerod
Ok i have some prices for multiple part order by laser cutting.. Parts:- 10off £15 each 25off £10 each 50off £7 each Delivery to me:- 10off £15 25off £20 50off £25 Its better, would there be any interest in this???by Davek0974 - Ormerod
Yes, understood, I would only use the stl's and my slic3r settings.by Davek0974 - Ormerod

Too low I had the same thing, the front of the fan housing is not vertical to the bed, it sags down. Get the adjustable X bearing all the way in, I also filed off the bottom of the fan duct a bit. Also make sure the brass end of the bowden tube is all the way in so the head is as low as possible. I also had to stick a thin steel tape along the X axis on the acrylic, don't tape the bearing or itby Davek0974 - Ormerod
I think you can see the issue in the picture attached. It looks like it changes every four layers but only on the vertical part, the base is smooth all the way up. Any ideas?by Davek0974 - Ormerod
