Re: Larger Bed (420x420) - Will this work? - 9 years ago

Thanks for the reply, unfortunately I'm up in Bundaberg, QLD. I'm not sure how well it would fare in freight.. I ordered a silicone heater mat from ali, just waiting on delivery for it now. Was just under A$70 for a 240v 500x500 850 watt heater.

Re: Larger Bed (420x420) - Will this work? - 9 years ago

Thanks for the insight. What thickness plate plate would you recommend? Would it be worth going to 8mm thick or would that be pushing the weight factor too much? I'll be planning on running leadscrews with anti-backlash nuts for drive the bed (im push more for accuracy and print quality then speed with this build), somewhat like your printer but with a 500mm3 build size.

thanks for the feedback. My only concern with those is being in Australia we have 240v AC but if I put in a GFCI that should add a secondary safety step in case of line damage. How are these compared to the PCB type heaters?

Larger Bed (420x420) - Will this work? - 9 years ago

Hi all, I'm currently in the planning stages of my next printer and I'm looking at having a 420x420 (or even 500x500) hot bed for my next printer build. What I'm curious to as can I power 4 PCB hot beds using dedicated power supply (24v 60a) with a relay fed from the printer controller PCB to switch them on/off, using one centered thermostat to read the temperature of the bed? (as per the attac

Re: filament finished before the print did... now can't get new filament through the extruder! - 9 years ago

I had this happen too, turned out a small amount of the old filament was still in the hotend just past the gear When I tried to feed the new filament in it pushed to the side of the old stuff, didn't push it in the hotend. Had to dissemble the hotend to push if through so the new filament was able to feed.

Re: SmoothieBoard Users - 9 years ago

Lots of good info here. At this time I'm leaning towards going a duet simply due to it currently being better on network and the expansion board. Arthur, is there any plans to do something like the expansion board with smoothie and when do you expect to roll out the updates you discussed?

Re: SmoothieBoard Users - 9 years ago

Quotethe_digital_dentist What will you be using networking for? Smoothie has it, but to me it seems sort of pointless. A 3D printer requires that you change or verify adequate filament, prep the bed (clean, level, zero, etc.), and remove the last print manually. Since you have to be at the machine to do those things, what's the point of networking the machine? While you're at the machine doin

Re: SmoothieBoard Users - 9 years ago

Thanks for the feedback so far. I'll look in to the duet as well. At this stage just trying to decide on which board to get. I am open to suggestions as long as the board meets the criteria I mentioned at the start. Network is a big piece so the better the network capability the more suitable the board will be. 2 extruders is a minimum but 3 would be great. Mostly I'm trying to find how us

SmoothieBoard Users - 9 years ago

Hi all, I recently bought my first 3D printer (Zonestar P802MA) and am loving it, however the limitations of my board on it (Melzi board) are having me looking to building a 2nd printer. Things I am listing as essential for my next build are 1) dual (or triple) extrusion 2) network capability 3) 32 bit board This got me looking / leaning towards the smoothieboard so I thought I would ask those
