When using belts for the Z axis you should install a counter weight to prevent it from dropping and you also need to make sure your firmware is set so the z steppers do not turn off between layers. Don't forget to monitor the heat coming out of your z steppers when you leave them on, they may need a fan.by thecrazy - General
I know this is an old thread but their site appears to be offline now. I get great results now with the filament I got from them (thanks to my heated printbed + elmers glue/water mix) Anyone know what happened to them or who manufactured their filament? Surprisingly their tolerance on 3mm filament was pretty good, made prints with it that show less artifacts related to filament tolerance than wby thecrazy - General
Wow, its been a while! had another of those "must forget about life for a while" kinda job to do. Yes I had tried keeping the same temp but it didnt help. The good news is I no longer have the problem but with the winter gone I am wondering if the hotter weather is responsible or the changes I did to the 1st layer heights and width. I tried messing with those earlier but it didnt seem to helpby thecrazy - Reprappers
The heat bed is at 55C for the whole print.by thecrazy - Reprappers
I have lowered my hotend closer to the bed and it seems to have helped a bit but it wasnt perfect. More testing required. I understand what you mean by the output being round but the extrusion width in slic3r for the 1st layer is set to 200% so there is some "squeeze" or something else happening cause way more plastic is being pushed out and the traces are flat and wide as you would expect. but eby thecrazy - Reprappers
Hi guys, its been a while. A side project at worked turned into a full fledge product so fast that I had to forget about life for a while DeuxVis, that picture youve posted is of the same printer but it predates my heatbed and 100% aluminium frame.

Did anyone ever get the design files? RRD promotes this is an open source project but I cant find any files, not even in their open source section on their site.by thecrazy - For Sale
Your absolutely right. Here are the details: Im printing with PLA at 190 1st layer and 185 for the rest. The heat bed at 55 for the entire print. I have a cooling fan but its not on all the time, its controlled by the Ramps board and only turns on when needed (small layers, bridges, etc.) The printer is a Mendel Prism with almost every plastic parts replaced with aluminium. The frame is very soby thecrazy - Reprappers
Thank you for your input, I have looked into it more closely and on the purple print its the 3rd layer that curled up. On the grey one its the 2nd layer with some area of the 3rd and its the same for the green print. I am a little bit confused, It would seem to me that no matter how squished down the 1st layer is, the trace would just be spread out more while being leveled by the hotend.

I have a problem with my printer that I just cant figure out. No matter what filament I use the perimeter of the 2nd or 3rd layer (seems like its allways those) curls up.

Hi everyone, This last year we were blessed with the birth of our 2nd daughter which resulted in having no time to invest in my 3d printing hobby.

Quoteaknapp Thank you for posting this! I have been looking for a way to better calibrate my machine for more accurate prints. I really appreciate you sharing this for those of us who could use the help. I will be using this method as soon as I get the chance. My pleasure. This community has given so much to me, I am very happy when I can contribute something.by thecrazy - Reprappers
Quotelazzymonk just found these would make life a bit easier. Not bad not bad! Can you imagine using that on all your axis and use its output to control the movement of the printer? That would be awesome. But it would probably be better to look into implementing some encoder strips. It would be much more compact and its basically the same thing.by thecrazy - Reprappers
QuoteMaxx Mayhem Quotethecrazy Quotelazzymonk What I have found out with all my years taking apart regular printers and copiers its that they are way more complex than our 3d printers.

Quotelazzymonk Did you know that you can interface directly with most digital callipers relatively easily. Just a thought. I noticed there was a connector on top of my calliper. I tough it would be for something like this. Ideally each axis would be connected to a calliper permanently and the printer would calibrate itself. But what I think will happen instead is that printers will start usingby thecrazy - Reprappers
Quotejbernardis Nice idea. Should be relatively easy to try out. I'd like to see a picture of the E axis mounting; I can't quite picture it. If I put the calliper into the slot, won't I be blocking the bolt from going through and tightening things down. What I'm gathering from this is that I mount the calliper above the extruder, and then run both the filament and the calliper through the cliby thecrazy - Reprappers

80 x 60 is low but if you check the comparison here its not that bad actually, could still be quite useful: What worries me a lot more is that they are selling it for 165$ and YES the guy is willing to sell one to me without those large 50+ orders. Also regarding the resolution, read this: Seems like the internals of the E4 are the same as the E8 and a firmware hack can unlock the full resoby thecrazy - General

In 1.75mm nozzles, the back pressure is lower than in 3mm nozzles. Which makes it easier for the extruder to push the filament through the tiny extrusion orifice. So, because of all this, one advantages of 1.75mm is that you can make a direct drive extruder with a nema17 stepper only. For 3mm you will need to get a geared motor and that is bigger = more weight on your carriage. I would be temptby thecrazy - General
