what if i use the main adreian design which is threaded but without thread , as i find it hard to find peekby karandex - Plastic Extruder Working Group
the slot drill is used to make push fit design , is it required to have.by karandex - Plastic Extruder Working Group
what is better sleeve design or push fit, also is it required to use slot or flatten the drill for pushfit ?by karandex - Plastic Extruder Working Group
according to me 1 )the problem with adrian design is the threaded ptfe part slips or breaks , right? 2)how is new makerbot hot end ? 3)i think its about releasing plastic at tip of hot end without any bend and melting , am i getting concept right ? so makerbot should be great i am thinking of making hot end similar to mendel-parts v5 but i read that is causing the problem. bot mill also uses it.by karandex - Plastic Extruder Working Group
can somebody figure out how to make makergear hot end, it seems its the best finally hot end compare makerbot nozzle vs adrians nozzle vs mendel-parts v6 or c5 vs makergear vs j head nozzle can you lathe offset ? because of j heads nozzle is machined offset. i was thinking adding two resistors by making it symmetricby karandex - Plastic Extruder Working Group
what is best hot end for wade? i have lathe so please give design which is better on latheby karandex - Plastic Extruder Working Group
any more suggestions ?by karandex - Plastic Extruder Working Group

i renamed config.h.dist to config.h and copied config.gen3 to config.h getting error In file included from /analog.h:15, from analog.c:1: /config.h:479:2: error: #error this config is marginally, and may be incorrect! please post in forum or via git any corrections In file included from /temp.h:4, from analog.c:7: /config.h:479:2: error: #error thisby karandex - Firmware - experimental, borrowed, and future
what does this mean in instructions Copy config.h.dist or config.yourboardhere.h to the config.h file. should i rename the config.gen3 to config.h or should i copy (not replace) contents of config.gen3 to config.hby karandex - Firmware - experimental, borrowed, and future
i dont have e axis , just xyz. so i remove that line it will compile and dont consider any m code ? in my gcode this line give me error T1M6 its on start so i have to replce them by G21 G90 every time, is there solution that it wont consider t1m6 ?by karandex - Firmware - experimental, borrowed, and future
the most ideal case will be, splinter firmware on gen3 or ramps with makerbots interfaceboard. that interface board is sweet. hey can any body make the teacup or splinter build for me with absolutely no extruder or heatbed code (but with acceleration). i need it for my cnc mill build, the problem is the gcode created by software like v carve or cambam have some code that gives error on replicaotoby karandex - Firmware - experimental, borrowed, and future
have you guys managed to run teacup firmware on gen3 with acceleration and run it on replicaorg? Have you manged to add lcd and interfaceboard also ?by karandex - Firmware - experimental, borrowed, and future
ramps or gen3 as usb to parallel for Tb6560 , i think title says it all. i have used gen3 with a3982 for cnc mill, so can i use ramps or any electronics for that matter to provide enable , step and dir to these cheap Chinese tb6560 ? why there is so problem using them ( i read a wiki entry about it)by karandex - Controllers
i tried teacup on my 644 but the problem is it gives error heater_1_pin not found or somthing , i decalred as -1 but the firmware doesnt work, in printrun gives start but no movment. i selected board as one, can you send me a ver with absoulty no extruder and heater stuff, just sd card and gcode interperterby karandex - Controllers
The reason i am doing this that i am making a cnc kit.I find it baffling that no one have come with a ver of firmware just for cnc movement and spindle speed control in replicatorg. And think of replicatorg, not all of my cnc users will be used to complex software like reprap software or python based host. thats why i insist on replicatorg not because its best, its easy to use and i just need basby karandex - Controllers
Hi I made a mantis type cnc ( actually 2). The i am using a3982 and sanguino to control it though repg. I have seen countless firmware and host software I apeal to all that please make a cnc friendly system of these wonderful resources My dream system 1. Replicatorg is must, repstrapper,reprap host software,etc.. is horrible. its not easy to use by all 2. Use of sanguino or arduino 328. No mega,by karandex - Controllers
So it is safe to use 24 v? I will add heatsink.by karandex - Stepper Motors, Servo Motors, DC Motors
i got new motors. these are nema 23 , with 2.6 ohms resistance, about 11Kg of torque. DOnt know other specs. Now i tried these motor with a3982.When the pot is adjusted to 1.1Amps it start to get warm.After 1.2 the motor makes some plasma blaster charging noise. ( is this noise mention in stepper driver 2.3 instructions?) . I know a3982 cant drive these motors to fullest but atleast they are ablby karandex - Stepper Motors, Servo Motors, DC Motors
reprap uses hybrid motor. All general motors are hybrid. Stick to metal to your mendel motor when turn off and tell me its is permanent magnet or notby karandex - Stepper Motors, Servo Motors, DC Motors
i have found a supplier near me can you tell me which is the best motor. I am not building a mendel , i am making a cnc. 12V Pc power supply a3982 driver i need most torque that can be obtained with above specby karandex - Stepper Motors, Servo Motors, DC Motors
so to get more from motors i need to give more voltage because of resistance, and from spec, my driver is only at 0.3Amps ?by karandex - Stepper Motors, Servo Motors, DC Motors
is 40 ohms resistance for a motor unusual. I cant deside that should i run these motors at 24 v. And the pot on driver is to limit current right? In short what to do to get most from these motors. PS how know from specs of motor that a3982 can drive it or not.I am a steeper newbieby karandex - Stepper Motors, Servo Motors, DC Motors
one more thing , is the torque to pps graph is more or less same shape if i changed it from half to full step or providing less volatge i mean if a motor is giving highest torque at 500pps in half step and 36v will the max torque(offcourse less) at full step 12v will be at 500 pps ?by karandex - Stepper Motors, Servo Motors, DC Motors
its got 6 leads the pc power supply is powerfull enough for these nema 17 motors, which give more torque half or full because with 15tpi the accuracy is not the issue can i chain 2 power supplies to give 24 v i think a3982 can handle that i will check current value the thing is the stepper motors are knock off of these the 47mm length model See what help you can give again thanks for helping mby karandex - Stepper Motors, Servo Motors, DC Motors
ok i am using some Chinese stepper motor on my cnc mill with following specs 12v 0.3 a per phase 3100 g-cm torque Using with a3982 same as stepper driver 1.2 . it got a pot but i dont know what to do with it. I am using 2 of them in full step as they have weird problem that when i give 5 v to there micro step pin from sanguino THEY GET REALLY HOT IN FLASH OF HALF SECOND. as soon as i turn oby karandex - Stepper Motors, Servo Motors, DC Motors
one more thing the resistance per phase is 40 ohms which i find bit highby karandex - Controllers

Hi this is my first post i am now building a mantis 9 cnc and want to use reprap electronics as i will need it in my future repstrap first of all i live in india so i dont have access to the kits and board except sanguino and arduino. i am going to design a board similar to alternative electronics of reprap like gen 7 and gen 2 on a board.
