I see an E -4 move in your second line which would retract. I don't see a positive 4 move to re-prime.
yeah, i was testing to see if thats why it primed before moving back to the spot but even without the -4 it still did, my guess is the firmware is doing the E axis on the G61 command for some reason even though according to marlin docs it should be limited to X and Y with

... it's not so dead, but it's an "oldstyle-forum", not twitter or a facebook-group, so don't expect prompt reactions
And most "used" members will only answer, if they could help substantially ...
not exactly new around here, but 6 days no answer, 4 before a reply = dead, thanks for the answer

Hello, I have been trying to get a simple wipe function to work after every layer to prevent petg blobs. the wipe part is working but my issue is no matter what I do, the extruder always re-primes immediately after moving to the wipe brush when I want it to re-prime once its moved back into position, my layer change script is as follows, any help would be appreciated.

while they are fixed length they can be scaled up or down as needed using the same printed parts. They are only shown at that size with measurements because those are the lengths needed to work with prusa i2 hardware, which at the time was the printer I had when designed so I could reuse most of my parts. I was more so posting it to show the counter weight idea to take the strain of the bearings

I know this is a bit old but for anyone looking for an idea for a fix to a cantilevered platform I designed this a while ago,

CoreXY Machines
I just finished my design of a new CoreXY (non crossing, two belts) printer that I've had in mind for a while now using readily available parts where i could. This is my first post in a couple years, finally getting some time to work on my projects again.
I had a few criteria to meet. all of these compared to your typical prusa i2 (the printer i currently have)
faster printing
more accuracy (in

a very interesting idea, unfortunately I am now working 7 days a week so development has all but ceased, I've been playing around with my pcduino to develop an all in one electronics similar to ramps, so between that and this all my free time is gone.

Cant wait to hear, im now finally getting around to finishing mine, my psu crapped out and found a steal on a coolmax 400 watt with 25 amps on the 12v for $15

Right now with the hearingbone gears it has the same if not slightly less play then stock wades gears but the gear slides nicely on the shaft. i was thinking i might be able to go even smaller with the clearance if i use nylon but im trying to keep this viable for everyone

It deffinatly wouldnt hurt having to many amps is never bad as the printer will only draw as many as needed, as for the threaded rod depends on where you live for 8mm in the US i could only find it at machine shops or a supplier for machine shops but where i got all the one cut to length including the smooth rod was on ebay from a machine shop for like 50

this could actually be very doable just have to come up with an offset extruder to feed two filaments, might make it in the next revision, im curently fighting with my printer to make it work

no it has homing, it goes great then goes all the way home and the extruder just keeps runing at max feedrate and dumps filament its only ever happened twice and its running perfect now i trippled check all my connections and they are perfect, infact they are entirely overkill there are two heavy gauge gnds soldered on the board an extra jumper from there to the bed mosfet which is a heavy duty 7

so i came home to my extruder making a horrendous noise and the x axis all the way home with plastic just dumping out, repetier shows it stuck at printing a layer no errors, this is the second time this has happened an im affraid it might cook something if it happens again no idea whats wrong any thoughts?

that power supply would barely be adequate for a regular heated bed and the would be pushing it. mines at 25 amps but i also modified the psu to output 13v because of some voltage drop under load, this is easy to do if you have a potometer near the sense line.

So i recently aquired a pcduino, essentially a mini pc on a cortex 8 combined with an arduino, it can run ubuntu while also running arduino sketches with arduino compatable header with enough output a to drive a ramps board because you would no longer need a sport for sd (micro sd is built in) and no serial connection as its built into the os.
I am currently trying to install repetier host to s

I'm currently working on installing repetier host on my pcduino, on a side note did you know these run arduino sketches as well as ubuntu at the same time, with arduino compatable headers meaning a ramps could be adapted to work theoretically, essentially an all in one minus the slicing as it doesnt have the processing power for that.

I thought the same because when i purged the abs the nylon mixed and stuck the abs very well, as for temp 120

I felt like giving nylon another shot after i got good with abs, turns out nylon sticks very well to a thick abs slurry on a heated bed, just felt like sharing as i couldn't find the topic about the bed material for nylon.

At that rpm you could do a huge gear reduction gain a good amount of torque while the motor itself is spining fast enough to use the positional feedback

after i give this one a shot i'll try that as i have some extra bearings, and see how they compare, ill have to see how big i can make the drive gear without overstressing the stepper, or i might try to adapt this

it would provide the exact same advantages of the bowden without the hysteria, also it does allow more clearance than the regular wades extruder when at higher z heights due to the motor not contacting the frame, when i did a simulation in inventor it allowed almost the full use of the print bed, and i don't see how its irrelevent saving weight on moving mass will always yield an improvment in pr

I thought about that the only problem is it put triple the torque on the square bar, increasing the friction for the sliding gear, as for the Z hieght I'm working on new vertices, but they might require cutting the threaded rod

I've seen those, the problem with multiple rods is the flex which i find there is very little with the vex rods as they are intended to handle torque, as for the last one that i liked the idea so I designed parts to actually accomplish it as it didn't seem to go much past his concept markup, What i hope to accomplish is making this easy for everyone and hopefully get some feedback to imporve the
