OK, I've spent the day doing some work on my recently purchased, used kickstarted Robo 3D. The learning curve is steep but I'm making progress. I've managed to print a few pieces of a top mounted spool holder although after completing the first piece I read some posts on here mentioning that they're a bit of a risk as the spool may fall and break the bed. I'm continuing to print the parts as a way to learn how to use the printer combined with the fact that it didn't come with any type of spool holder other than the clear acrylic rod that came with the kickstarter spool holder, which is only part of that spool holder.. Forgive me if I get my terms mixed up, I'm still a noob! Also sorry for asking so much in one post. For reference, I decided to follow the Robo video for how to set up the printer so I'm currently using Matter Control for software. Anyway, now for some of my observations and questions. The printer has: 'drawer slide' Y axis non metal J-Head glass heated bed single Z axis switch on right side Some questions: The heated glass bed doesn't work. I have checked the option in Matter Control, but it won't heat. I unplugged the wires and have about 1.4ohms resistance between them. I plugged the wires back in and clicked pre-heat in Matter Control, but there was no voltage on the wires. I tried this with the hotend and it does show 12v across the wires while heating. I swapped the thermister between hotend and bed, and proved that part works. I'm thinking maybe it's a firmware or software issue but I don't know what to check next. The printer came with parts of an E3D V6 hotend, but not the complete kit. The picture shows the heatsink and heatbreak, there is also the translucent blue fan holder and a brass nozzle. I have already ordered the 'block and sock' upgrade kit, so I'll be getting those pieces soon. The few installation videos I've seen show a white tube that goes into the top of the heatsink, but there is no place for that in the one I have. I also don't have a new heating element and don't know if I need one. I do know that I'll need a new fan setup but don't know which one people prefer or if I can print it with the current state of my printer. The printer came with an LCD but once again, not a complete kit. It's a reprap discount smart LCD with SD card slot but not the XXL that is more common for Robo owners. This one has the controls to the right of the screen, not below. The LCD did not come with the adapter to fit the Robo PCB, so I have ordered one and it's on the way. Not really a question here, other than I can't seem to find an STL file for a nice case with mounting setup for this screen that fits on the front of the Robo like the type commonly used for the XXL. While printing spool holder pieces tonight, I eventually noticed melted filiment around the bottom of the hotend. This lead me to discover the cooling fan for the hotend is missing. I did remember the seller mentioning something about it, and he included some 3D printed pieces that look to be a modified version of what the fan mounts to along with a couple extra parts to cool the parts on the bed. I'm thinking that some of my current printing issues are being caused by the hotend getting too hot due to a lack of cooling. I'm thinking I shouldn't use it anymore until I can get a fan in there. I've got the printer cooling down now, so I haven't looked to see what I'm missing other than the piece that holds the small stock fan and probably the screws that hold it in place. What type/size screws are these? I've got all the hardware to upgrade to the R1 bed leveling (compensation) system, I just need to print the new Z brackets and start assembly. I guess that's enough for this post! Thanks in advance for any assistance!
