Re: Upgraded to 1.1.9 and z homing is reversed. - 4 years ago

Hi Robert, Thanks for the advice! I gave it a try and it didn't work. All the axis were reversed. Oddly enough after I reverted the direction back to what I had it before, it started moving in the correct direction. I didn't change anything other than the Invert values. Awesome, that's one problem solved. Now, I'm running into another issue. The Z probe offset is not working. After I home z

Upgraded to 1.1.9 and z homing is reversed. - 4 years ago

I've been struggling with this for a few days and just can't figure it out. I had a really old build of Marlin V1 from 2014 and I wanted to replace the problematic servo probe with an inductive probe. Printer worked fine before the upgrade besides the inconsistent servo probe. I added the (blue tip lj12a3-4-z/bx) inductive switch with a voltage divider and m119 shows it triggering as expected. I

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

I think it's from too much heat. If it weren't for the auto bed level. It would have taken me a lot longer to get usable prints. So i'm circling back around now and trying to get the machine mechanically leveled first.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

I originally used springs but did not like how the bed didn't stay leveled. I bumped the bed once by accident and I to re-level it. I ended up using standoffs for a solid mount. My CF plate is pretty much useless now. It's really warped now. I'm going to experiment with an aluminum heatbed to see if I can get this damn thing leveled. I'm also hoping to get the E3d hotend installed soon. Life got

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

Quotegadget_greg As with everyone else, bed leveling is a bitch. I have the slightest hump in the middle of the heat bed which seems to be exacerbated by the carbon fiber plate. Also, I must have missed something in the config file because my extruder will not respond to commands from the LCD-controller. I swapped motors and stepkicks around and still nothing; all parts are functioning properl

Hey Tech2C, that's interesting about using the PID for the heatbed. I might have to give that a try and see if it fixes my random alignment issues.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

Man... that sucks about all the shipping damage that's occurring. Although it seems like with the new packaging, things are getting better. Still almost seems like a roll of the dice, because it's going through china post. Roll the dice and that's how many times it will be ran over by a truck before it gets to you.

QuoteRSA27 I just got the kit and everything looks ok so far. I got the new packaging and it doesn't appear that anything was damaged. I will try to put up pics in the next couple of days. I have a question for those who have the kit : How did you attach the x end stop? The endstop supposedly attaches to the x idler using 2 screws - but they appear to get in the way of the plug - how did you

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

It's just a standard 12v 30A relay that has a 12v trigger. I connected the solenoid up to D8 to trigger it. The Heatbed shouldn't draw that much. 10-15amps depending on the resistance of the heatbed.

I fixed my shorted out heatbed issue. It ended up being the through hole plating for both positive and negative are connected to the large copper layer. I just took a utility knife and cut the traces. Bed now reads 1.0ohms. However, I'm still getting uneven heating in the bed. One side of the bed is a good 10C lower than the other half. The side that's lower happens to be connected through the r

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

jprochnow, Sorry to hear about your damaged package. I'm honestly surprised mine made it with such little damage, considering the box arrived pretty crushed. It sounds like yours was literally ran over by truck. Replikeo sent my replacement parts out right away. It took roughly 2 and half weeks to get them. However in your case, it sounds like you can't even start assembling it.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

yeah.. I'm getting a dead short on the pads. 0.1ohms. I'm also running the heatbed directly to the power supply through a relay, since the PTC always trips when the heatbed is wired directly to the ramps board.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

I have the E3D V5 hotend. I didn't know a v6 was going to be released, I would've waited for it. I haven't even installed the hotend yet, since I'm still trying to get the heatbed issues sorted out to print in ABS. I also inspected the carbon plate replikeo sent me. It's completely warped. It's visually twisted. So far, it seems keeping the bed level has been a real challenge for me. Maybe the

Hrmmm.... I'm going to test that theory out too. I'm using a clone reprap discount full graphics controller. but i've been mainly printing from the usb port. Also, I'm using Marlin for the firmware with some autobed level code changes to show more info during probing.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

I never thought about the bull dog clips causing the pair to warp. I noticed my carbon plate is bowed now compared to when I initially installed it. I noticed this with the auto bed level feature. I can see a topography of the bed. I also never thought about the carriage acting as a heat sink. Duh... I'm getting some cork to isolate it from the stand offs

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

Yeah, I didn't use the included power cable either. I didn't like the idea of not having a ground in case the power supply cooks for some reason. I used a power supply cable and cut off the end.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

Thanks for the tip. Yeah, I'll give that a try. I had already adjusted all the drivers via a multimeter when I finished building it. Everything was fine until I added the relay for the print bed. I bet having the bed hooked up directly to the power supply is drawing too much current and could be causing a voltage drop to the drivers, hence missed steps and layer shifts.. I will say that printin

I found one problem, if I turn on some hungry device (soldering iron, stove etc.) Y axis start shifting pretty hard.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

That really sucks. I order quite a bit overseas and that has always been my fear that it gets lost or stuck in customs. Hopefully it's not stuck in customs because the box is destroyed. Have you tried calling the post office? Hope they find it for you.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

I've been printing with the carbon plate, and it's significantly flatter than the glass I got from matter hackers. There isn't nearly as much compensation happening during a print and first layer adhesion appears to be quite a bit better.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

Not yet... I still haven't replaced the wires on the bed yet. I'm not sure if the PTC fuse on the ramps board can handle the current that the bed draws. Right now, I have the bed wired directly to a relay and using the the D8 pin to trigger the relay. This setup seems to work fine, just not as clean as i would like it.

I got my replacements and carbonfiber bed on saturday. I haven't tried printing on it yet. I'm still experiencing some first layer adhesion problems on certain prints, I'll give the carbonfiber plate a try. Can you clean the carbon fiber plate with acetone? Will it eat the epoxy?

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

I ended up getting rid of the springs because the bed would shift during a print, I ended up using some m3 10mm stand offs I had laying around. I also installed the y belt holder with nuts on the top side of the bed.

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

I agree that the packaging needs to be better. I was surprised more parts weren't broken when I received my package. It looked like a truck ran over it. I'm still waiting for my replacement parts. China post can be real slow sometimes. Check over your m5 Z rods. Mine were pretty bent, I bent them back as good as I can. Still not happy totally with it. Need to pick up a stainless rod and some bras

Re: My Replikeo Prusa i3 Rework Build - 12 years ago

I ordered a roll of ABS from the same place I get PLA from (Push Plastic) to test. The replikeo roll varied quite a bit over a meter or so. From 2.89 - 3.02mm. From the failed test print, it wasn't really black, more like gray. So I figure I try out a more "quality" roll. So far it has been difficult to print ABS on this machine. Mostly due to the Mosfets dying while trying to heat up the bed to
