Have you tried bolting a dremel or router to your RepRap? Can you engrave and drill PCBs? Or cut wood, or ... steel? (Or do you have a commercial mill or CNC router?)
Fan assembly fouls on foldback clips - 11 years ago
I'm finding that the bottom of the fan assembly is fouling on the foldback clips that hold the glass plate on the heated bed. So I dare not try printing anything, or testing the automatic bed compensation, because any attempt to home the head or move it between the compensation points when it is lowered will result in a crash. It looks to me that the problem stems from two causes: 1. The X-idleby dc42 - Ormerod

My SD card problem (failing to run config.g at power on) did not appear to be related to low voltage either. I measured 4.97V on the 5V rail.by dc42 - Ormerod
Problem building Duet firmware - 11 years ago
I'm trying to rebuild the Duet firmware so that I can sort out the problem with the IR sensor. I've downloaded the firmware source from and also installed all the libraries at as mentioned in the README file. But when I try to built it under Arduino 1.5.5 I get a lot of errors, starting with:: In file included from /Platform.h:2, from /RepRapFirmware.h:52, froby dc42 - Ormerod
Re: Ormerod commissioning problems [SOLVED] - 11 years ago
I bought a Maplin 4Gb Class 10 SDHC card today to use in place of the one supplied, and that has fixed the problem of the Duet not executing config.g on power up. In summary, the problems I had commissioning were due to two issues: 1. The SD card supplied takes longer to be ready after power up than the firmware allows for. 2. Too much ambient light (especially incandescent light) prevents thby dc42 - Ormerod
Re: What is RepRappro policy on self-repair of Duet boards? - 11 years ago
OK, thanks for that. I don't have any other issues with the board. USB is working, and Ethernet works provided that I don't connect with Pronterface over USB first - but I guess that is a software issue. So I might fix it myself, depending on how annoying the need for USB power gets.by dc42 - Ormerod
What is RepRappro policy on self-repair of Duet boards? - 11 years ago
I'm aware that as the owner of an early Duet board with two resistors incorrectly mounted, I can return the board for a replacement. But RepRapPro is now closed until next year. What is the policy on owners who have previous experience of SMD soldering attempting to desolder and resolder the resistors themselves?by dc42 - Ormerod
Re: Repositioning the Z axis on the X axis bed. - 11 years ago
I came across this too. The instructions originally said 205mm/125mm and that is what I used. When I came to commission the unit, I found that the hot end fan did not clear the main electronics box when the carriage was lowered, even with the electronics box positioned as close to the Y motor as possible. Part of the problem is that the fan supplied to me does not have the recesses for the screwsby dc42 - Ormerod
Re: Ormerod commissioning problems - 11 years ago
Hi tru168, I don't think a Hall sensor would work well here. The point of the IR sensor is to allow bed plane compensation to be done by probing the 4 corners of the bed. If you used a Hall sensor, you would need to use 4 magnets under the corners of the bed, and you would have to set the coordinates it uses to place the head very accurately over them. I think the solution is to modulate the IR Lby dc42 - Ormerod
Re: Network connection - 11 years ago
Hi Treth, I'm running my Ormerod connected to my laptop, which is wirelessly connected to my router. To get the laptop talking to the Ormerod via Ethernet, I had to bridge the wired and wireless network adapters, so that both can use the same subnet i.e. 192.168.1.x. Bridging the network adapters under Windows is very easy, you just open the network adapters page in Control Panel, highlight bothby dc42 - Ormerod
Re: Ormerod commissioning problems - 11 years ago
I just found why the proximity sensor wasn't working. I sent G31 commands to get the proximity sensor readings. With the head in the middle of the bed and a long way from it, I was getting a reading of 844, and it was very sensitive to anything (e.g. my hand) that I placed under it, even if not very close to the sensor. The Ormerod is on a table with a 50W halogen bulb in the ceiling above. I turby dc42 - Ormerod
Re: Ormerod commissioning problems - 11 years ago
I've just bench-tested the proximity sensor, applying +5V to the leftmost pin (the one with the pink wire on the photo), ground to the centre pin, and looking at the voltage on the 3rd pin on a scope. It seems to be working fine. Output is close to ground initially, rising to beyond 4V when I hold a reflective foil surface close enough to the sensor.by dc42 - Ormerod
Re: Ormerod commissioning problems - 11 years ago
Hi Markus, thanks for your response. I don't think the X-axis homing problem is down to lack of reflective tape. When I try to home the X axis, it doesn't move at all. When I try to home the Z axis, it drops the head a few mm and stops. I think the problem is that I had the sensor board connections the wrong way round. I've just traced the circuit, and the only component I found on the proximityby dc42 - Ormerod
Re: temperature sensor problem - 11 years ago
I got exactly the same thing. I think the commissioning instructions are wrong and you should only get the temperature error messages if the thermistors are not connected. A little later on the commissioning instructions tell you to connect to the Duet using Pronterface, and to expect *correct* temperature readings.by dc42 - Ormerod
Ormerod commissioning problems [SOLVED] - 11 years ago
I've been trying to commission my Ormerod (#072) for most of the day. The current problems are: 1. I can't get Pronterface to consider the printer is online without resorting to a cumbersome procedure. It looks like the Duet firmware (updated to latest as of today) is not going into Marlin emulation mode. When I try to connect to it in Pronterface, it sends out the M105 commands and the Duet resby dc42 - Ormerod
