really cool work. I haven't seen a new concept in a really long time. Last one was the simpson series of printers. Just out of curiosity wont it be simpler to have the tension rods move inside bushings , thereby eliminating the support arm? Just a though. I would love to make one of these. I have built scara plotters in the past but the inverse kinematics of those are kind of difficult to work wiby ekaggrat - General New Machines Topics
great work . I have been following your work since long time. Cant wait to see it work.. Have you seen this? multi color active mixer . this guy has it figured out but now has kind of disappeared from the web . The impeller in this seems to be the secret sause . thats y there are no images of the impellerby ekaggrat - Developers
cool . nice work. but why no jumpers to setup microstepping ?by ekaggrat - Developers
i have been playing around with a core t as it is called . i made a mistake of moving the entore gantry up for the z axis which i have recently changed. overall it is better to use linear rails videoby ekaggrat - Mechanics

have you take n look at the makelangelo firmware by marginallyclever robots. It has a six axis robit built in and the firmware is very easy to change . github linkby ekaggrat - Polar Machines, SCARA, Robot Arms

@balajiramani you can always make a a custom bed easily. Use nichrome wire ( available with all electronics/electrical shops) embedded in liquid silicone gasket( available at all vehicle spare shops). or u can use silicone blanket heating wire taped to the bottom with polymide tape. Calculate the resistance according to the voltage and wattage needed. All my custom printers use silcone blanketby ekaggrat - Delta Machines
for corner lifting the old fashioned ways works better,, just add one or two layer thick circles of 10-15mm dia on the corner and after printing u can just clip them off..by ekaggrat - Reprappers
i can comment on it having built 2 gus simpsons 1.5 ( not the original but the one with the pulleys ) Yes it is buildable and prints very well but calibration is a PITA . also it is very silent. So if you are upto the chalange do it .It can never be a practical a go to printer as it is again i say hard to calibrate! instagram instagram instagram forumby ekaggrat - Developers
@ikcl sorry for being harsh. but if you were intending to contribute to the design a little more upfront work would help the process. most of the discussions are started with a little base work done. Sure you are welcome to contribute. and a person with a fisher would be in a better place to respond to your query,, ps: you can easily grab the model from github to play around with . the fisherby ekaggrat - Fisher
have a look at the bigbox by e3d.. they have a toolchange gcode which puts the head in a bucket and purges all the content on tool change. then when it selects the new hotend it primes it in the bucket and starts the print , zero drool what so ever. the down side is that the printer has to be big enough for the heads to go outside the bed.by ekaggrat - Reprappers
at least make a proper model or a 3d model or do a basic fea analysis to prove the point.by ekaggrat - Fisher

did you even read the patent? it is nowhere near what richrap did . they are doing a far more complex process which involves blending the filament way before it enters the exturder.by ekaggrat - General

sure you can make it and gain experience and then move on thats all there is to it.. fyi a corexy with lasercut cut steel parts and aluminum frame can be put together in under 300 dollars provided you know the right places!by ekaggrat - Developers
Sorry if I offended people but I have built a printrbot jr in the past and it worked well but not as good as a rigid frame corexy . I do try new mechanisms even if they look not good enough . I have been building a gus lately . Also I meant a prism i2 was not a very good option not the i3 . Sure you can try substandard mechanisms .but promoting them as superior is plain wrong .by ekaggrat - Developers
i dont understand y people play with this printrbot jr derived machine.. it is not worth the trouble .. rather even a prusa is not worth the trouble . after a few years of using a prusa and then a mendelmax i changed to a corexy completely made out of aluminium extrusions and laser cut steel plates. the machine was a breeze to assemble . It just 10% more than a printed parts machine and aligningby ekaggrat - Developers
panucutt has already done that with re-arm. the idea of gen-7 was to be able to diy it easilyby ekaggrat - Next Wave Electronics Working Group
hi, I intended to make the generation 7 using a lpc1114 in lqfp package.. I have a dip conversion pcb. But for a test i soldered it on a dip conversion board and connected a serial cable a reset button a jumper on pio_0 . I tried getting it in programming mode by pressing the rest button but just cant get it to program. I tried different buad rates but it just wont respond. Is there any otherby ekaggrat - Next Wave Electronics Working Group
any ramps board can run a scara printer . just dont go crazy with highly segmented models.. most firmwares now support a scara printer. the easiest firmware to modify for scara is smoothieby ekaggrat - Polar Machines, SCARA, Robot Arms
right now manual leveling.. the prints i have are very acurate as the mother printer is acurate and not a crappy printer.. The thing is strings are not super acurate and tend to stretch . so if you change to belts it will be better, as then the steps per mm calibration will not be required which is another headache and depends on the accuracy of the vernier used. i will be adding a probe and getby ekaggrat - General New Machines Topics
ok cool.. i can live with openscad.. I knew the base needed to be accurate so i built it out of 2mm laser cut steel sheets.. that way the hole spaceing is super accurate and the plates are super flat. Also as a bonus they are conductive.. In hind site i think a better approach would be carbon fiber 4 mm plates.. i am leaning towards teacup now till i get a smoothie. But i will have to test it oby ekaggrat - General New Machines Topics
i think right now it needs a better way to calibrate.. the hardware verison 2.5 is just fine and very easy to put together. The hardware has a lot of compliance due to the geometry which limits the speed. I can have a look at your files and suggest changes. I am bad at openscad as my background is more of design than programming. I think a better way to making the files would be freecad or inventby ekaggrat - General New Machines Topics

the mks is ok for testing i guess but people dont have good experiences with it . i would go for a re-arm with a ramps or a proper smoothieboard..by ekaggrat - General New Machines Topics
i created a virtual model of gus in grasshopper 3d to see wwhat causes the domical effect ... seems that it happens if you get the max arm lengths wrong in the firmware that effect is created.. so i will be trying to add a offset in the arm length in the firmware ( i amusing marlin as i am using cheap ramps for now ) and see if i can get that corrected.. will report in a day or two. which firmwby ekaggrat - General New Machines Topics
to be clear they are cycloid gears.. what i meant was eventually once it runs smoothly it could be simplified to the point of being either injection molded or resin casted.. if there is one cool printer i want on my desk to show off it would be gus.. as far as error is i can report back once i get the new arms printed.. even the current arms which i have can take out good prints .. u can see iby ekaggrat - General New Machines Topics
