If you have a Michael's or similar Arts & Crafts store they have sheets of cork in roll that is 24x48x5/32, I got one for $11 and unlike the "cork" board from Home Depot it is actually 5/32 of cork.by WZ9V - Delta Machines
Having struggled with a delta and its calibration fits as a first printer (huge mistake) I finally circled back to a simple i3 type design (Robo R1+) and life has been so much better. Lot's of delta topics revolve around calibration, dimensional accuracy and the tons of processing required to get that at high speed (32-bit boards). I'm hoping with the Robo's help and very careful alignment (metby WZ9V - CoreXY Machines
For the non-motion parts you could get them pre-cut from Misumi. For the V-Slot required for the motion parts OpenBuilds only sells the standard lengths mentioned.by WZ9V - CoreXY Machines
Mutley3D, can this be used on printers that probe the bed with a nozzle heated to print temps?by WZ9V - General
I also downloaded the Think3DPrint3D calibration instructions for their Kossel. Mine is using a Duet 0.8.5 like theirs, only significant difference is their probe is the DC42 IR one and I'm using FSR's. The procedure will be the same but I know my offsets and their calculation will be very different. Now that I have a SeeMeCNC Onyx heat bed and mhackney's adjustable FSR mounts I'm hoping I canby WZ9V - Delta Machines
Yes to the controller board. My new setup uses a vertical free floating bed with 1/4 Melamine support. That should help with the flex/tilt I had with glass/heat spreader only. Unfortunately I'm being slowed down by the need to switch the bed to 12V while the rest is 24V. Have the power supplies and SSR needed, just need to get it all wired up and laminate the PrintBite to my glass. I think Iby WZ9V - Delta Machines
After many modifications I'm trying to see if I can get consistent readings with FSR's so that my Duet's calibration comes out right. My old setup seems to have been possessed by demons and would NEVER give me a workable firmware calibration. In the process of trying to "fix" it I've tried various new FSR mounts, bed holders, etc. I think I finally tracked the problem down to a combination ofby WZ9V - Delta Machines
All of the calibration guides I've seen suggest using a piece of paper (0.1mm) as a feeler gauge. This would mean that when you issue X0 Y0 Z0 it will actually be X0 Y0 Z0.1 should I be subtracting out that 0.1mm so that the hotend is actually at Z=0? Seems to me that if I don't the Slicer will make a 0.2mm layer 1 at 0.3mm in height.by WZ9V - General
This hot end with DC42's sensor and Multley3d's Flex3Drive looks like it would an interesting combination.by WZ9V - General
There are times when I think maybe I should just buy another glass plate.by WZ9V - General

Are the mount holes compatible with the holes on the aluminum Kossel effectors? If so I want one in 24V. I don't think you left enough room for DC42's IR sensor ;-)by WZ9V - General
Thanks. I have the bulk of it off and now I'm down to film that just won't let go. I'll go at it with scrubbers and Acetone.by WZ9V - General
I've tried Goo Gone Pro but it's just not dissolving the 3M 468MP adhesive. Can someone recommend a solvent that will dissolve the adhesive. I'll trying to cleanup a glass plate for a new layer of PEI but having a devil of a time getting rid of the old adhesive.by WZ9V - General
I have a Geetech RAMPS board and they are rubbish. You want specifics 1) Low quality PCB 2) Poor soldering quality 3) 16V capacitors (limited to 12V but specs say can do 24V) and a regulator not designed to work at 24V without overheating. I also have a Taurino RAMPS 1) Good PCB 2) Good quality soldering 3) Parts rated to work at 24V (35V capacitors) and regulator QuoteDjDemonD This is my poinby WZ9V - General
Which version of the web control should we use with this update? Quotedc42 I have now released 1.09x-dc42 (i.e. it is no longer a beta). This contains two bug fixes since beta3. One caused the Z probe and temperature readings to be inaccurate on Duet 0.8.5 boards, the other is to fix a network reliability issue. If you are using 1.09x-beta3, please upgrade. You can do this on the Settings tab oby WZ9V - Duet
Wouldn't the Replikeo Duet 0.6 at $50 be considered pretty affordable? Even at $135 from Filastruder the Duet 0.8.5 is not bad I think. Unless you are getting super cheap questionable quality parts the $150 dollar range does not seem unreasonable.by WZ9V - General
Thanks Tinchus and 3Dex Ltd , that's the sort of info I was looking for. Are there particular brands of ABS that seem to work better than others? I've been using the Inland ABS from MicroCenter but I've seen some good stuff about Hatchbox.by WZ9V - Printing
Can someone point me to good information on tuning my slicer/firmware settings for being able to do decent bridges with ABS? I can do some decent ones with PLA but have not been able to figure out the very different tricks needed for ABS.by WZ9V - Printing
Pronterface can also use a virtual tty to Smoothie over the network. QuoteKoko76 I'm not advocating pronterface, what I'm advocating is different and better. Perhaps if you had experience with what you are talking about you might have a different opinion. I bought and used both boards. Have you, or are you just speculating?by WZ9V - General
You don't have to go to all the way to line voltage. If you get a GOOD DC SSR you can use the onboard FET to switch larger DC loads. The trick is finding a GOOD DC SSR. I got lucky and mhackney pointed me to one from Auber Instruments note the 0.006 ohm on resistance which is far better than the cheap ones using BJT transistors.by WZ9V - Duet
BeagleBone is better suited for this type of control since it has the onboard PRUs to handle real-time tasks. MachineKit and BeagleBone are standardizing on a kernel with real time extensions.by WZ9V - Controllers
Power = Voltage * Current Power = Current(squared) * Resistance Current = Voltage / Resistance As DC42 said power is not a constant, it depends on the Voltage and Resistance values. Since they control the Current and Current is the main driving factor in power as you can see I the two equations above the power changes as you change the voltage.by WZ9V - Delta Machines
Unfortunately most DC SSR listings hide the one piece of information that would help which is the on resistance. If it's around 0.1 ohm it's a design using a bipolar transistor or really crappy FET, if it's around 0.006 ohms it's a much better FET design. I have one of each, using ohms laws Crappy SSR at 17A = 28.9W lost to waste power (Heat) - 10% power loss in SSR Good SSR at 17A = 1.7W lostby WZ9V - Delta Machines
I would not risk it on an Amazon SSR. The one I posted has a proper FET design with a low on resistance. There are a lot of cheap ones using a BJT that will get VERY HOT. I tested one that at 17A load was reaching close to 70C with the huge heatsink. Even with the heatsink and a fan it was still around 40C. The one I posted barely gets warm at similar loads.by WZ9V - Delta Machines
If you have a delta printer, what do you like about it? Simple easy construction, fun to watch. Which delta printer do you have? Is it pre-build or a kit? Kit - Ultibots V-Slot 250 What firmware do you use?

David, a further refinement of my LED thinking would be a header that brings out all the onboard LED indicators. We could then use a ribbon cable or whatever to the front of the machine or control box and make circuit board to mount the indicators. This would allow us to bury the board and its blinking lights deep inside but still have the comforting glow of LED indicators where we can see themby WZ9V - Duet
I'd recommend one of the below SSR's and a separate supply for the heated bed. The RAMPS FET will then only need to drive the SSR (which it can easily do) the SSR will isolate your heated bed from the RAMPS board which would allow you to pump a bit more power into the bed (within reason). For instance you could go 15V or so for the bed (at 12V terminals) while still running the RAMPS board atby WZ9V - Delta Machines
