Using those fans a few day's now, working perfectly ! Using it with http://www.thingiverse.com/thing:45236, so the fan's don't toch the bushing blocks. Thank you for sharing !

Hello all, When I use Cura 13.06.3 and/or 13.06.4, I found a strange suport material issue. I've set the support material amount in Cura to 30%, the place of the support material, in relation to the object, seems misplaced. Anyone has the same issue? Regards, Harold

Maybe I can help you with the wheels. If you can send me the 3D file (split up in wheel and tire), I can give you a price for it. I'm living in the southern of the Netherlands, so sending it to you won't be a big issue. Regards, Harold Reedijk

No problem, hope I can help.... Yes, I'm using the Ulticontroller and a relay to control my HBP. I'm running the latest firmware 1.5.7 and it's working fine. I'm using a separate power supply for the HBP also. Regards, Harold

Count me in for the next batch! Currently rebuilding my UM within a aluminium frame, one of the missing parts are the pulley's!. I'd like a full set (10x8, 2x5). Regards, Harold

Here are 2 more 3D models: http://www.thingiverse.com/thing:29513 Below with direct drive modification: http://www.thingiverse.com/thing:10956 Regards, Harold

I'll definitely come around! Regards, Harold

Well, It seems the elephant foot nearly has been gone.... I'll keep tweaking on it, but it's at a acceptable level now. Thank you Owen for your time and patience! Regards, Harold

I've taken Owens advise to use kapton tape, I had a roll laying around of 200mm wide. Last night I've made the same print, with heatbed at 70C, nozzle at 210C, fan at 25% and a speed of 60mm/s. Result was even worse then before so I made a few tests with the temps and fan. After those tests I can conclude that using the fan (in my case) is the main cause of the elephant foot. Eventually I came close to the result I want to have. In the pictures below I've used a heatbed temp of 54C, nozzle at 210C, no fan and a speed of 35mm/s. Tonight I'll try not to set the first layer to be thicker that the other layers. See how that will turn out. Keep you posted. Regards, Harold

What temp do you advise for PLA and ABS with a mirror and kapton tape? Regards, Harold

So if I understand it correctly, I need to to place kapton tape on the mirror glass. I can perfectly level my bed, got a dial gauge for that. I'll use kapton tape this evening, I'll post the results back here. Thanx Owen! Regards, Harold

Hello everyone, I've got a question about printing with a heated bed. On the photo's you can see that the print is not straight upwards. No matter what I set on temp on the nozzle or bed, I'm keeping the same results. If I set the bed lower than 60 C , the filement won't stick to the mirror anymore. If I set the temp higher, the first layer will melt to much and having a sharp 0.1mm edge as result. I also tried to print with the fan on, the result was even worse than on the photo's. The print on the photo's was made with a nozzle temp of 210 C and with a bed temp of 62 C with filament of Faberdashery, color pearl white and printing with the fan off. Has anyone any idea where to look to get the print straight? Regards, Harold

I don’t know about the red light, I didn’t looked at it.... There must be something wrong with the thermistor or the connectors.

Do I understand you correctly, you do see a room temperature on the UM controller, measured by the thermistor? If you do, check if you got the relay connected the right way, see the schematics below (also the + and - from the terminal block): Regards, Harold

Hello spiruline, I think you need to twist the wires of your thermistor on the PCB board. I also control the heatbed by the pcb with a relay. Regards, Harold

Hello spiruline, When my UM controller went blanc, I've installed the default firmware back with Cura. Below the link of the hex file I use now: https://dl.dropboxusercontent.com/u/1911369/Shared%20Files/UM_1.5.7_with_heatbed_firmware.zip I cannot give any guarantee that it will work on your UM, but if you have a 'regular' 100K thermistor and a PCB version of 1.5.7, it should work. Let me know if it did. Regards, Harold

Thank you gr5. I've tried it and got it working now. When I uploaded the firmware to the UM with Arduino IDE, the ulticontroller keeps blanc serveral times when powered on. At the end I've got it working. Regards, Harold

Can anyone help me? I've installed a MK2a heated bed on my UM, the only thing left is a firmware ajustment so I actually can use it. I've already installed the latest firmware file on my UM that came with Cura 13.03. Unfortunatly Daid's builder is offline, so I cannot create the new firmware file, with heated bed activated, the easy way. I've searched across many forms how to create it manually, I'm lost. What I can find are only pieces of what to do, not the complete actions to do. Does anyone have a good description how to build the needed firmware, or even better, has a hex file that I can upload to my UM. (I use a regular 100K thermistor). Regards, Harold
