@Treth, DeuxViz Instructions: You DO need to install the Arduino IDE 1.5.5, to include the Arduino Due drivers. Also, the Arduino IDE Serial Monitor works very well at getting basic communication and testing done, as described in the instructions. Virtually any version of Pronterface *should* work with the Duet. However, Pronterface won't respond correctly until the config.g on the SD card isby reprappro - Ormerod
Hi Treth I've done the updates you suggested, though still need to add a couple more pictures. You should have received 5 x M4x16mm button head socket screws and 3 x M4x8mm button head socket screws. You only need 4 and 2, respectively, but we packed one extra of each fastener. What quantities does it say on the fastener bag (7 of 8)?

Hi Markus Usually, yes, JP9 should be jumpered to get 5V power to the logic side of the board from the 12V supply. However, we're investigating an issue: some boards don't have 5V from the 12V power, even when JP9 is jumpered. However, they should work fine, so long as 5V power is supplied via USB.

Hi pault We've been investigating this problem.To work from the 12V connector, JP9 DOES need to be in place, to supply 5V to the rest of the board. Without it, the logic side of the board can only be powered by USB. However, you may have a short circuit, caused by a mis-placed connection, or the 12V to 5V regulator may not be working, or both. You should be able to test the board by unpluggingby reprappro - Ormerod

Dave I think you have a recent kit, with black belts? And the X and Y pulleys are the same? We currently use MXL belts (pitch = 2.032mm) with a 17-tooth pulley. The steps per mm should be the same for both axes, and are calculated as follows: (Motor steps per revolution x microstepping) / (number of pulley teeth x pitch of belt) = (200 x 16) / (17 x 2.032) = 92.635 Josef Prusa's calculator heby reprappro - General Mendel Topics

Email reprappro tech support on 'support at reprappro dot com', and we'll work out if it's a machine problem (short circuit drawing too much current) or PSU (probably the more likely).

Hi Dave The voltages shouldn't cause this issue, though you can check them if you want; I set the reference voltage (0.6V), while flashing them with the latest firmware, before we pack them into kits.

Hi Paulid Once you have connected to the Melzi in Pronterface, press the reset button on the Melzi. You should then see the startup messages from the printer, including the eeprom settings - if you copy them into a reply here it may help diagnose the problem. If you don't see any message, how did you install Pronterface? Did you install from github? If you did, you may be missing part of the inby reprappro - General Mendel Topics
Hi It sounds like the axis is sticking on one side. This can happen for a number of reasons: frame alignment, tight bushings, x axis too long or short between the Z smooth rods. I have written a guide in the troubleshooting section, see: Also, check that the Z motors turn together with nothing attached, ie undo the motor couplings, it could be a wiring fault.

Hi Johan It sounds like you might have loaded the Mendel firmware settings on your board, rather than the Huxley settings.

Current RepRapPro Huxley and Mendels use a fibreglass-reinforced black rubber MXL belt, 1/4" (6.35mm) wide, on a printed 17-tooth pulley, giving 92.635 steps per mm. Older machines, pre March 2013, use a steel wire-reinforced polyurethane T2.5 belt, 5mm wide, on a printed 14-tooth pulley, giving 91.429 steps per mm. We changed over to the MXL belt because it is quieter, lighter, just as strong,by reprappro - Reprappers
Hi junkelsplitsy It certainly isn't behaving correctly. It sounds like you have done most of the tests I would usually expect. It's possible that the firmware settings have got corrupted, which you can set back to default by sending the following to the Melzi in Pronterface: M502 (lots of text in the log window) M500 ("Settings stored") Then press the reset button on the Melzi.

Sorry for the delay. We have uploaded a single STEP file with all the SolidWorks parts in it - mostly the X axis. You can download it, open it in FreeCAD or any other CAD program, and split out the part you want. Ian RepRapPro tech supportby reprappro - Reprappers
I have documented different extruder positions (new style extruders) and updating the Legacy Mendel with the new axis here: For the Y axis, you can lower the bed a bit by removing the belt adjuster, and using clamps similart to the Tricolour.

@srayner02: The simple fix is to wrap a couple of layers of Kapton tape on the linear bearing to make the friction fit more positive. As PLA is quite slippery, it can slide on the metal of the bearing. Make sure the linear bearing is moving smoothly on the rod; refer to the instructions on cleaning and lubricating them during construction: "Check that the linear bearings slide smoothly on each oby reprappro - Reprappers
Yes, we use SolidWorks 2013 at RepRapPro. We are in the process of converting all the files to STEP files; they should be in the github repository later today. @NormandC: Not sure why it would open in such an old version of Solid Edge, but I would be concerned that some features are ignored or not renedered correctly.

Hello, I am sorry you have gotten so frustrated with your Huxley. All RepRapPro kits ship with 0.5mm nozzles. This has always been so. 0.3mm nozzles are available as an upgrade.by reprappro - Huxley

@Suljo: Yes, you can set the steps per mm either way. But it's easier to do it with M92 than editing and flashing the firmware. If you want to do it in firmware, the steps per mm are set in the configuration.h tab; look for the line that currently says: #define DEFAULT_AXIS_STEPS_PER_UNIT {92.635, 92.635, 4000, 660} And change both '92.635' numbers to the numbers I gave you above.
