Quotenebbian Either of these slight misalignments will have drastically more effect on accuracy than using ball joints vs Traxxas. This is so true... Quotenebbian No matter how good your measurements are, you will always have a small amount of effector tilt, so an underslung effector will minimise the distortion on printed parts. I've measured this, and is why I went to all the trouble of makby Redemptioner - Delta Machines
Put some pictures up of your setup and especially the area running from filament spool through to the hotend. My guess is you have something restricting the filament pathway that is exaggerated/reduced when the head is in certain positions or making certain movements, in other words you have and issue with over extrusion that is reduced sometimes giving good prints. If you have a flying extruderby Redemptioner - Printing
The simple answer is no, but you can get some mosfest and connect them up to some spare channels on your duet and then write Gcode for the that channel to change the PWM output to then change the RGB colours. Just make sure you get ones that work off a 3.3v signal.by Redemptioner - Experimental and Hobby
A silent fan equals no airflow, the people changing out the fans for the 40mm noctua fans are significantly dropping the cooling on the heatsink and you often see them start having "clogging" problems as these fans have have Zero static pressure which results in very little cooling when you try to compress the air into the 30mm fan shroud.

No one has said magnetic joints are not a legitimate connection for delta's, it has only been pointed out that rod ends are a better mechanical joint for multiple reasons. @DC42 Your effector flexes when used with a flying extruder, there is enough flex to allow the extruder to pull enough load/flex into the effector to cause nozzle to crash into the print on the release of every retraction, itby Redemptioner - Delta Machines
now you have me interested....it has the potential to really shorten up the arms while maintaining incredibly constrained joints with no maintenance. I agree that we are talking about basically nothing that is going to make any difference. I like the wood as the support arms, the dampening the wood will add to vibrations is a brilliant idea and some great engineering.by Redemptioner - Delta Machines

Quotedc42 I can only assume that either you have no experience of magnetic joints, or you have only experienced ones that were not properly constructed. Properly made magnetic joints - such as the ones I have, made by Haydn Huntley (the variant with machined Delrin ends) - have zero play.

Sorry but that is simply not true, most people go to mag balls because they think they look cool and think of it as an "upgrade" and few change because they need to be able to change the effector out regularly (or think they do). Rod ends are far more stiff and have ZERO play in them compared to mag balls, people who have issues with rod ends do so because they use garbage rod ends (i.e. Traxxisby Redemptioner - Delta Machines
So 145*C bed temp (160*C at machine) and a thin film of baked on PVA and I have good adhesion, was self released off the bed when it cooled but I can feel that it has stretched the Printbite slight as there is now a "ripple" in the area the print was attached. Will cycle the bed at that temp again today without a print to if it will heal itself.by Redemptioner - General
I would not suggest the mag balls unless you really want to make a lot of effector changes, they centre "ok" but they definitely do not print as clean or as accurate as solid rod ends especially at higher speeds (and speed is a big reason for getting a delta). I also would not get too carried away with underslung effector setups, it is pretty rare to high max build height on most deltas, normallyby Redemptioner - Delta Machines
The blockage is 100% caused by the cold side of the heatbreak getting too hot. There should be no reason you don't run the cooling fan on the heatsink when ever the heater is on, so don't wait the 15mins before turning it on Having baked the hotend at 270*C without a heatsink fan for some time now, I would hazard a guess the heatbreak is ruined.

Any one printing standard Polycarbonate? I normally print PC on PEI with a thin PVA layer (to act as a release agent as it micro fractures the PEI sheet all around the part edges and lifts the PEI from the glass bet on cool down otherwise) and print at 160*C bed temp and 305*C nozzle temp and enclosure temp at 60*C no fans no brim or raft but a 10 wall wide skirt 0.5mm from edge of print.

Hopefully you have held off buying a printer until now as they have come down significantly in price and have gone up in quality. $350 will get you are really nice 2 colour printer with a 220mm square build volume with an all metal frame.by Redemptioner - Australia, Brisbane RepRap User Group

Well any1 that has been printing for some time could tell you the benefit of having springs under the bed is not just for bed leveling. You only need to have a bit of warping or wander in calibration to have the head crash into the print or bed itself causing damage or destruction of print, then multiply that my a machine running at 250mm/s and we are talking catastrophic issues.Springs under theby Redemptioner - General

I might of been clear, the build plate on the Tevo LM is held on by 6 M5 bolts that use a set of spaces to hold the build plate away from the base plate (hexagon build plate). I have removed 3 of these M5 bolts and replaced the spacers with springs to allow me to adjust the bed perfectly square with the towers but adjusting the remaining 3 M5 bolts. The holes let over from removing 3 of the M5 boby Redemptioner - General
So I got completely sick of how crap the BL Touch is for both accuracy and repeatability on sensor/bed height detection let alone the fact it will randomly drop the probe and ruin prints.... Considering this crappy sensor uses a bit of heatshrink to set the probe height and length to hall effect sensor, when it is mounted just in front of the hot air coming off a hotend, it is just a crap designby Redemptioner - General
Have you got any of these kits still available for free for testing in order to make up units/test for new printers? Just finished designing up a set for the Tevo Little Monster to suit the 27mm and 20mm discs and now looking to give it a test run. The design incorporates some heat shielding/insulation as well as keeping the piezo as far away form the heated bed as possible. Initial tests showby Redemptioner - General
