I custom designed and built a dual extrusion 3D printer and have been using it for about 6 months or so. It's my 2nd printer. My first is a Folgertech 2020 i3 kit that I've redesigned to 2 or 3 times over. It is now closer to a Prusa MK3 than the original kit it came from. I like having the option for dual extrusion, and I do use it on 10% of my prints or so, but there are some drawbacks to theby markag - General New Machines Topics
I built a new custom designed printer and fired it up for the first time late last week. It is a dual extrusion machine, and I've designed with extra travel in the X direction so both nozzles can reach 100% of the build surface. I also entered the nozzle offset in the marlin firmware, which seems to be leading me to have some issues using Cura. Because the offset is set in the firmware, I have tby markag - General
Just to close this out. I discovered my problem was a bad cable to the stepper motor from the driver. Swapping to a different cable resolved the issue. It is still strange that a resistance check between the start and end pins on the connector for each strand showed no open lines, but apparently the cable was still faulty.by markag - Firmware - Marlin
I am building my 3rd custom 3D printer, but this is the first one I've done with dual extruders. I got the printer powered up and running for the first time last night, but I have some questions on the behavior of the two extruders and wanted to clarify. General Info: I am using a MKS Gen 1.4 Board with DVR8825 stepper drivers. Not that it matters, but I've got two e3D titan extruders mounted iby markag - Firmware - Marlin
Hey guys. I just installed an overhaul for my extruder and hit end assembly. I upgraded to an E3D V6 about a year ago, and I never was happy with how to mount it with the stock x-axis mount and MK9 extruder. I really like how well the original prusa printers print and manage cables. They have one of the most space efficient extruder setups I've seen. It's almost artistic how neat and tidy theiby markag - Prusa i3 and variants
I knew there had to be a solution. I wasn't sure if I could pull power from an external source, or if it had to come from the RAMPS board. I already have a hacked up cell phone charger from a different arduino project that I may look at using.by markag - Prusa i3 and variants
I apologize if this has already been discussed... I've added a bltouch to my 2020 i3 printer. I also have the full size LCD on the printer. I've noticed that if I run the printer untethered from a USB connection, my LCD flickers when the bltouch probe is extending or retracting, and the auto bed leveling doesn't work. If I plug in the USB cord to my raspberry pi or PC, I don't have that issue.by markag - Prusa i3 and variants
Got my kit in today. Everything seems to be in order. My boards don't look too bad, but I did have a question on the arduino board in the image. It seems like I might have a solder bridge, but it also looks like it might be intentional. Looking for some input there. I also noticed my hot end is not square relative to the extruder. Question is, should I care? How do I fix it? I've never seeby markag - Prusa i3 and variants
Thanks for the info. I had actually seen your blog before, and I've bookmarked it for reference when I build mine. My kit shipped today, so I will receive it next week. I'm looking forward to getting it going. I'm lucky to have the access to 3D printers at work. I've not had a chance to actually get hands on with a printer yet, but I have designed many parts and have had them printed over the pby markag - Prusa i3 and variants
I just ordered one of these printers with the Folgertech black Friday coupon. I'm looking forward to receiving it and starting the build. I'm a manufacturing engineer by trade, and an very comfortable with assembling things, so I'm not expecting to have issues with the build. But, I know that the are always little things that pop up here and there. What drew me to this kit specifically was theby markag - Prusa i3 and variants
