Alright guys had some free time to work with the printer some last night. I unclogged the hotend, and polished up the upper portion. Fired her up set the temp to 185c and manually extruded. Loaded up the 40mm to 30mm adapter and hit print. With the temp at 185 it prints no clogging and the part came out solid as a rock. I let it cool down and I removed the part and cleaned up/removed the supportsby lokiwizz - Prusa i3 and variants
the hot end is set at 200c fan on always blue translucent pla 1.75m. All speed settings default in repeater. I don't know what other information would be of help so pls ask and I will do my best to answer Again thanks for the great support.by lokiwizz - Prusa i3 and variants
Well I got home fired up the printer, ran the same print and by about layer 5 or so no more extrusion. The hob bolt just grinds away at the filiment. I stopped the print end let everything cool down so I could pull it apart for photos. i could not get the photos to link correct with out brake n the internet so i will try and add them as attachments So any thoughts on this I think the hot end isby lokiwizz - Prusa i3 and variants
Good to hear you sorted it out now if I could just get mine to print more than one time without a repetitive clog think I'm in the same boat as you and need a bigger fan and better ductby lokiwizz - Prusa i3 and variants
Alright guys still having a clogging issue. I started out last night printing a 30mm to 40mm adapter for my fan and duct. The print was mostly a successful print could of used some supports. So I sliced it again with some. This is when it clogged. started the print did not make it past the first layer. So I un clogged it, set fan to always on. Still clogging. I will try a print again tonight anby lokiwizz - Prusa i3 and variants
Like I said before I'm no expert but from the looks of your jam it looks like the filiment is getting hot and melting up were the gears push it in the hot end. Again no expert but I think you need a fan pointing at the upper portion of the hot end. My be someone with more experience will chime in.by lokiwizz - Prusa i3 and variants
That if funny I also experienced the exact same thing as you described found one end stop was plugged in wrong. Then again like you found that they would only move one direction. I noticed in repeater host that it was saying it was at the end stop Preventing it from moving to save time I try everything software firmware still the same thing. Must be hardware. I found out that I had mixed up theby lokiwizz - Prusa i3 and variants
I am also a 3d print noob so you can take this or leave it. I also just some what finished a build and was to having jams. Mine was jamming just where the hotend and cold end meet. I found that it was from excessive heat traveling up to the cold end melting the filiment to far up. once cooled it would not remelt. Solution was better fan and fan shroud on the hot end. Some info that my help otheby lokiwizz - Prusa i3 and variants
Fix for now all setup was default 200c .3mm so on and so forth. Just had the walls test print successful. Think the problem was hotend got to hot before printing from all the testing and the bs fan and shroud was incapable of sufficient cooling replaced for the walls test and so far so good. As always thanks for your time and helpby lokiwizz - Prusa i3 and variants
Well it printed sort of??? Got calibrating and ran some test prints none worth letting finish. Went back to calibrating esteps set for hot end pid auto tune hot end I have had the nozzle clog twice. It's not in the hot end but rather where it and the cold end attached not shore what happening. Any thoughts ?by lokiwizz - Prusa i3 and variants
All right guys getting close. She is all together now all axis move heated bed working hot end works thermistors reading. Ran it through a quick dry run. all that is left is calibration. hope to have a test print by the end of the day. Ps I went back and looked over the pinout it in fact turns out I was just dead wrong lol. As always thanks for the help. Chrisby lokiwizz - Prusa i3 and variants
Quotebigfilsing Well thats good news ... How can the pin out be wrong ???? its all very clear and has worked for many people for a considerable amount of time !! Or is that just a smoke screen for less than ideal wiring harness haha funny funny no I will post up the actual pin out vs the listed pin out tonight to be clear. but in short I should have conected the dots when I ohm'ed it the many tiby lokiwizz - Prusa i3 and variants
Alright guys worked on it last night. First tested the psu, 12v to almost 13v no load. Then with the got end as load right under 12v mid to upper 11s. So I would say the psu is not it. The new drivers and my scope came in. I them took the advice an broke out the bread board, set up a simple circuit along with my arduino uno. Pulled one of the steppers off along with the drivers. Low and behold mby lokiwizz - Prusa i3 and variants
Quotebigfilsing Quotelokiwizz Little update to list the psu specs. Supernight 360w 12v 30a This would be sufficient as long as it is capable And in good working order? Should be OK looks like a standard unit. There is sometimes a small trim pot near the terminals that allows you to adjust the out put voltage but that's normal not needed as they are usually set at the factory during testing.by lokiwizz - Prusa i3 and variants

Orders some replacement drivers along with extras also picked up a pocket o scope to be continued......by lokiwizz - Prusa i3 and variants
the voltages on the steppers I thought were correct, that's why i did not think the the psu wiring was at falt. Little update on the motor wiring (A1 is to A) (A2 is to A) and so on for the B side. Now i ohm'd them on my lunch break (I love living close to work) (A1 to A2) = 12ohm's and (A1 or A2 to com = 6ohm's), and is identical for the other coil (B side) here is a link to the data sheet onby lokiwizz - Prusa i3 and variants
On a side note the jitters seem to be strong but with nothing to compare to Its not clear to me. Maybe some pics and video are due.by lokiwizz - Prusa i3 and variants
Thanks guys all of these questions/suggestions are welcome. I will ohm the motor again tonight and post back the findings, I do have them wired a to a1, a- to a2, b to b1, b- to b2. The other two wires are labeled com and took them to be the center tap on my unipoler steppers. I don't believe the power wireing to be the problem as it is wired just like the ramps scimatics show with the two 12v raby lokiwizz - Prusa i3 and variants
Quotebigfilsing Easiest way to test is to use the test Marlin firmware to see if your motors work. Remember before loading to put your X& Y carriages in the middle of their travel and the Z at least 20 mm off the bed. The test software doesnt look at endstops or anything else just runs the motors backwards and forwards. test code Its unlikely ( but not impossible) you have blown all 4 driverby lokiwizz - Prusa i3 and variants
Yes that's what my thought process was as well. This is beginning to be two steps forward one step back got marlin all set up hooked all the electronics up to test again. Found that my motors are not moving as should. think my harness my be wrong after all. When I comm and any motor to move it just jitters back and forth never moves in one direction. The pin out for my motors is not listed asby lokiwizz - Prusa i3 and variants
Ok thanks looks like i will be heading to the hardware store for some m3x8mm On a side note i have confirmed my lcd working with the examples in the u8glib by adding this line of code ( U8GLIB_ST7920_128X64_1X u8g(23, 17, 16); // SPI Com: SCK = en = 23, MOSI = rw = 17, CS = di = 16 ) as seen here youtube video on this set up.

Lititle update (sorry no pics yet) made up a harness for a stepper motor, connected heat bed and thermistor, hotend and thermistor, end stops, lcd screen, wired up the psu and tested everything. Psu working ramps/arduino look good also. Loaded the ramps test firmware to light the lights jog the steppers.

QuoteViper97 I tore my machine down... changed out some pieces and I'm putting it back together this week. I'll see if I can get it together and grab a shot. I know this had me scratching my head for a bit. I'm assuming it's the Z axis that has you flustered? Yes your assuming correctby lokiwizz - Prusa i3 and variants
Mine came with the one you are talking about. I can't seem to find a good solution with it though, how did you mount yours as I have tried it every way I can think of.by lokiwizz - Prusa i3 and variants
all right ran into another little snag last night, mounting the end stops. mine the connector is covering the mounting holes. im going to de-solder them and straiten the pins and re-solder them (basically rotate the connector 90 on the board). the other problem is with this mount not clearing the x axis this one here haven't figured a workaround for this as my extruder is shorter than the averageby lokiwizz - Prusa i3 and variants
Well I fixed both the rod and the extruder carriage binding one new rod and some file work on the carriage and all is free now. Basic frame motors and end stops in place, on to the electronics now hope to have it printing this weekend. Pics soon to show you guys the progress so farby lokiwizz - Prusa i3 and variants
