Re: PEI Sheet - Clear - 7 years ago

I got mine from an aliexpress seller called '3D Factory Store'. Search 'PEI sheet' on Ali to find it. Biggest Ive seen is 300mm x 300mm but I would say if you message the seller he will do 350mm dia no problem for you. He was very responsive to messages when I was talking to him. Alternatively if that is a no go you could get a 406mm x 406mm sheet from 3D Prima and cut it down although it is qu

Re: PEI Sheet - Clear - 7 years ago

Ok so I've spoken to the seller and they are adamant it is PEI. They sent me the data sheet for it too. Its Duratron PEI apparently and after a bit of a google it is available in amber, black, white and custom colours. Ive installed it and tested with ABS - It works like a DREAM!!!! Panic over and finally a material that just works with ABS! Whoo-hoo.

PEI Sheet - Clear - 7 years ago

Hello I have just taken receipt of 'PEI sheet' for my printer bed but its clear and glossy on both sides. Anything I see online is claiming to be amber in colour, glossy on one side and matte on the other. Has anyone heard of clear PEI that is genuine PEI?? Thanks

Hello DjDemonD Unless I start my script with M302 S1 M83 etc. etc. My extruder motor will not work at all. However when I do the movement of the print file is not right.

Re: Filament Dump Start Script - Cura - 7 years ago

Ok, I got a chance to test this out quicker than I thought I could. I added the M82 command as you have suggested and ran the file. It move to dump, dump itself and the move to print worked a treat. Once it started into the print the movement looked good and like it should be however the extruder no longer moves. I tried again by adding the G29 E0 code after the M82 command and tried again how

Re: Filament Dump Start Script - Cura - 7 years ago

Quoteo_lampe After M83 and all the purge stuff, you have to send M82 to tell the extruder to work in absolute mode again. I'm also missing a M109 S command to heat up the hotend before purging, or is it a syringe extruding cold pudding? Thank you very much!! I will try this later tonight when I get a chance. As for the temp question no its not, lol, I always set my temps independently on the m

Filament Dump Start Script - Cura - 7 years ago

Hi guys, Im having real trouble with writing my own custom delta start G-Code script to perform a filament dump before the print starts. I have an Ultimaker 2 and it does it as standard. I really like this feature and would like to get my delta to do the same. I have been trying several different things but cannot get it to work. To be honest my delta has just been sitting in the corner for a w

Picking Power Supply help - 8 years ago

Hey Guys I am looking for some advice on picking a power supply for my delta project. I have done a lot of reading online but I am very confused when it comes to electronics. When It comes to picking a power supply I was thinking about using a 12v 33A 400W PSU as per a delta machine I have currently. However in my limited knowledge of electronics I thought that the PSU must at least equal the

Bed high and low issues - 9 years ago

Hey guys I am trying to help a fellow Kickstarter delta kit backer to get his machine up and running. I have suggested everything that I can think of and we're still stuck so need your help. The issue is that he is getting two low spots (0.8mm) between towers opposite towers X and Y towards the edge of the bed but a high spot (0.5mm) in front of X at the edge of the bed.

PLA for Kossel build? - 10 years ago

Hello again guys I am planning my first Kossel Build and I'm trying to figure out if PLA is suitable for printing the plastic parts? I have read quite a bit online and getting mixed results. I have found some companies selling kits that use PLA parts and some the use ABS parts. Also some sites that say PLA is fine and some that say stay away. Therefore I thought the best idea would be to ask h

Re: Delta bed high and low spots - Need help - 10 years ago

Hello Janpenguin Thanks for the photos. Just to clarify the problems you had with the uneven bed levelling was due to one or more rods being the wrong length?? This are kind of similar to what I am seeing

Re: Delta bed high and low spots - Need help - 10 years ago

Quotehercek Ok, so one rod is about 0.35 mm different from the others. My guess is that it should cause at most about the same error in z-height (i.e. about 0.35 mm). The error will be different on different locations of the bed. Anyway z-height wrong by 0.35 mm will result in your first layer not sticking on the places where the head is too high. This wrong rod will also lead to rotations of the

Re: Delta bed high and low spots - Need help - 10 years ago

Also just to mention, I swapped all the rods around before measuring them. Tower Z -> Tower X ->, Tower X -> Tower Y + Tower Y -> Tower Z etc and re checked the test print (200mm dia circle) The movement did not change and it was still high at one side and low at the other. I swapped the rods around several times and also rotated the rods 180deg (end at carriage -> end at platfo

Re: Delta bed high and low spots - Need help - 10 years ago

dc42 and hercek I did not make these rods, it was a kickstarter kit I backed and received. I have checked the rods again just now using your idea hercek about mounting them on a piece of wood and using a middle nail to get overall length as my callipers only measure 150mm max. I have now found that my rods are 280.3 instead of 280 but more importantly 1 of them is shorter than the rest by abou

Re: Delta bed high and low spots - Need help - 10 years ago

Thanks for all your help guys I have done what you said vreihen and my STEPS_PER_MM value is fine. I marked all 3 carriages and moved the effector down by 100mm using Repetier host. Re marked and measured and they all moved exactly 100mm. I also moved the nozzle to 0,0,0 and marked it. Then moved Y +100mm and re marked. Measured and it was exactly 100mm too. One thing that has changed however i

Re: Delta bed high and low spots - Need help - 10 years ago

Thanks dc42 and hercek I have looked this morning at the various things you mentioned. My printer has 20 teeth pulleys, GT2 belts with 2mm pitch, Wantai Stepper Motor (model 42BYGHM809) 0.9deg and a DRV8825 Kliment version Pololu driver set to 1/32 bit stepping according to the Kickstarter creator. I get this to give a STEPS_PER_MM value of 320steps/mm (400 * 32) / (2 * 20) = 320.0 I have a

Re: Delta bed high and low spots - Need help - 10 years ago

When you say that the diagonal rod length is incorrect surely this has to be the exact length of the rods and therefor cannot change? or can you alter this value to trick the software and force it to print flat? Ive measured my rods and the firmware value is correct. Thanks

Hi Guys I have been having A LOT of first layer problems with my delta printer (Kickstarter kit) I have calibrated and re calibrated using Repetier host and the manual 'paper calibration' and still the first layer is showing high and low spots. Generally it is high in front of each tower and low between them. (See embedded pic for best description of this effect) I have researched online and
