there was a warning about if i had my z probe defined on the wrong pins my arduino could burst into flames and burn down the national forests. can someone give this config.h file a look over and make sure i'm not going to toast my printer, it's the folgertech kossel 2020 revB all aluminum with the inductive bed sensor, thanks in advance!by ProfessorBean - General
@capacitor Do you still have a copy of your working Repetier firmware for the kossel 2020 rev b? i have tried several iterations of it and can not seem to get the Repetier firmware maker to output a working firmware file for my machine, either there are errors when compiling or it says the file is too large and doesn't leave enough space.by ProfessorBean - Delta Machines
So some design implements on the Simple Delta, First after printing either set of stl files (6 piece / 12 piece), which are still on John_sl 's github, for the top and bottom, omit the smooth rod, just use the 2020 aluminum extrusion then second, print a set of carriages and effector head for the kossel those have everything needed for the GT2 belts and the rollers ride nice in the 2020 t slots,by ProfessorBean - Delta Machines
Quoteforyst You may need to use RepetierHost (free printer driver software, and decent) to set them then. Once they're set, they should work regardless of what printer driver software you're using in normal day-to-day printing (like, I had to set mine using RepetierHost, but have been toying with MatterControl as my main print driver, since RepetierHost abandoned mac a few years back). If you'reby ProfessorBean - Delta Machines
Quoteforyst If it digs/floats in a concentric pattern (i.e. floats in the center, digs on the edges) then your concavity is off, which is fixed via DELTA_SMOOTH_ROD_OFFSET in Marlin or PRINTER_RADIUS/ROD_RADIUS in Repetier. If it float/digs in a linear pattern (like the right half floats above and the left half digs in) then you'll need to do better physical bed leveling and/or endstop adjustmentby ProfessorBean - Delta Machines
awesome, thank you all for the tips, i have everything calibrated now where it will kind of print, except if i were to print a 50mm circle 25mm of it digs into the bed and 25 of it kind of floats above the bed (after it auto levels)... i tried paul_delta's repetier firmware, however after i added my measurements and what-not, after it was compiled it told me that the firmware was too big, and usiby ProfessorBean - Delta Machines
QuotePurpleSensation You may have dimensional error on the pieces, and the print head may be oscillating, so if the probe z-height is oscillating also. It happened to me, I solved it with a self made design off head which use the nozzle as probe. I am having the same issue, how did you go about using the nozzle as the probe? what do i change in my config.h file to accomplish this?by ProfessorBean - Delta Machines
i was going to use "paul_delta"'s repetier firmware however when i compile it and get ready to upload it, it says the firmware is using too much memory(EDIT: too much memory in the printer) and that may cause errors, can i safely ignore this error message?by ProfessorBean - Delta Machines
Quotedocpayce @Professor: Looks fine to me, honestly. I would still suggest to use the GUI to set your configuration.h up: http://www.repetier.com/firmware/v092/ It's just so helpful. Look out though: If you changed variables manually using Arduino GUI, you may have to re-type them in the firmware tool. lol i keep trying to use the gui on repetier's website however i seem to have been bitten byby ProfessorBean - Delta Machines
i am having trouble figuring out what settings to put in the repetier firmware tool on the website. i cut the rods to as near to 240mm as i could (+/- .05mm), the z height is somewhere close to 282mm(+/- 1mm), i am using the Mega 2560 R3 (the clone blew up so they sent me a legit Mega 2560 R3 board) with ramps 1.4 controller and i have the blue tipped inductive bed probe and the aluminum heated bby ProfessorBean - Delta Machines
so how do i incorporate the settings for my 2020 folger tech kossel into paul_delta's repetier firmware? there are probably more, however those are the ones i am stuck at as of now. From the folger tech: //=========================================================================== //============================== Delta Settings ============================= //===================================by ProfessorBean - Delta Machines
I am also having trouble with my folger tech 2020 kossel clone, when i first uploaded the rev b firmware from folger tech the machine tried to kill itself by homing towards the aluminum bed, i turned the switches in the firmware and got it to home but when i try and use the inductive probe to level the bed it goes crazy in this kind of upwards spiral..... anywhere i can get properly programmed fiby ProfessorBean - Delta Machines
Not quite dead yet, i still have that old simple, i slowly worked kinks out and tuned it however i found that my particular model of simple came with laser cut birch wood that the two rod holes for my Z axis were cut off center to one another so no matter what i did there was no way possible to ever fix the printer so it could print the parts for a simple delta version, thus i fell into the conunby ProfessorBean - Delta Machines
QuoteRTurnock I just discovered the root cause of problems with my extruder has been too low a current to the motor so the gear would not drive the filament. Have to run the motor hot and cool it with a fan and heat sinks. are you sure? your hot end may just be clogged. have you tried cleaning it(i mean full disassemble remove any and all plastic bits), and soaking it in acetone? from my experieby ProfessorBean - Delta Machines
@RTurnock In my experience, the gear sent by printrbot for the direct drive extruder, can be used with either 1.75mm or 3mm filament, however there a few things to note, many of the wooden parts on the printrbot simple v2 need some attention with sand paper, files maybe even a dremel tool, the Y sags and causes slanted prints so you have to level your bed relative to the Y axis, then there isby ProfessorBean - Delta Machines
Quoteglennswest Is there a BOM for Simple-DR? Ie how many parts I need to print of each component. What "Vitimins" are needed? i don't want to answer for JohnSL, but I’ll explain from my perspective, appears if you’re not using the simple to print the delta, then you print 6 main platform parts,3 top 3 bottom, then you print off 12 of the rod ends, one carriage, the bearing sleeve/belt mounts,by ProfessorBean - Delta Machines
QuoteJohnSL Yes, all the parts are designed to be printed on a Printrbot Simple, which has a 100mm x 100mm bed. I don't know the maximum height off the top of my head, but it's less than 90mm. lol FYI you can squeeze 100mm on z in the printrbot simple....by ProfessorBean - Delta Machines
@johnsl That looks a lot better for stability, did the first set wiggle too much? Thanks on the upload! oh and which version of solidworks did you use? i have access to SW 2013 SP0by ProfessorBean - Delta Machines
Looking good John, when the time comes, are you going to upload the solidworks files too?by ProfessorBean - Delta Machines
@JonhSl you know you might be able to kill any stability issues by creating a slide lock system between all the pieces so they would lock together then be bolted, sort of like a dove tail or some other equally strong wood working joint, however i don't know how difficult that may be to add and subsequently print... this little delta may not be "simple" enough for the simple... that is if you getby ProfessorBean - Delta Machines
lol well now that he has had the opportunity to use and test them, a half a year later, @leadinglights, what is your opinion on the Igus rods? any good?by ProfessorBean - Delta Machines
this is an awesome design, in-between the "wings" (the left, right and motor housing) on each set you can add 3 straight printed pieces on the top and bottom sets to scale up the size of the printer, then add taller rods, longer carriage arms and larger printbed, theoretically it could easily go up to a 600 mm build volume maybe more.by ProfessorBean - Delta Machines
awesome, it looks really good, and as far as publishing the files, github would be good, you could throw a set onto thingiverse, as that's where I initially checked for a replacement for my "simple", and i suppose where the "noobs" go first. Keep up the good work!by ProfessorBean - Delta Machines
I tried the red nylon trimmer line sold at "WaL-MaRt", printing at 200 C seemed good, got a lot of poping gassing and oozing , i think the best print happened at 195 on a custom cut fiberboard bed.by ProfessorBean - General
Looking very good there john. are the raw files your working with available yet? you know so the rest of the community can tinker with the design too.by ProfessorBean - Delta Machines
I say just add an extra clip to each side, so instead of having one on each side you use 2 one for each "wing", that would make the bed nice and solid, it is coming along nicely, I really like the design, that also makes it easier to replace damaged sections should a stepper motor over heat to the point it warps and/or melts the mount, or any other accidents that may happen and damage a section.by ProfessorBean - Delta Machines
HAHA hilarious, I found the added weight of my heated bed that I added to my simple caused belt slippage on the Y axis when in printed in honeycomb pattern fill, plus caused the belt to slip on the Y, then the Y axis drove into the end stop switch and caused a wire to break off which caused a fault in the simple so everything works and the circles are round again. i am realy looking forward to upby ProfessorBean - Delta Machines
@JohnSL HA I have read and read and asked for assistance on the Printrbottalk forums and no one has yet to help me, so I just do trial and error stuff. on another note, I am part native American and like my ancestors that killed an animal and used EVERY part of it, I am a fan of reusing EVERY part of the simple lol right down to the nuts and bolts, since you had already had an amazing idea to tby ProfessorBean - Delta Machines
That's AMASING! it's like you reached into my brain and pulled out exactly what I was imagining! I am still fighting and arguing with my simple trying to convince it that printing a circle is WAY better than an oval, I'm making small steps towards a nice acceptable circle.... i hope to soon start printing the machine that will replace the simple used to print it, now that would be the ultimateby ProfessorBean - Delta Machines
Thanks John, I'll be keeping an eye on all your pages, if you figure out how to cut up the pieces so they will fit on the simple's print bed do let us know. I have one of the "newer" simples with the direct drive extruder.... I think I might try a Bowden extruder for the simple to see if I can't get it to print true circles instead of the slight oval I'm getting now. makes it tough to "replicate"by ProfessorBean - Delta Machines
