Looking at the d-bot at the moment. It's on thingverse and ooznest do kits for the cut lengths of extrusions and a bundle of mechanical/motion parts. I'm going to prepare the builds to see how much filament it needs today and hopefully get the go ahead to progress with the project. Cost wise if using the steppers and Duet 0.6 from the 2014 Ormerod 2 the price looks to be around £500-600 without hby WesBrooks - Ormerod

I can see me making sure the remains of work's Ormerod are suitably recycled... ;-)by WesBrooks - Ormerod
Hi All, By accident I have landed myself a tight time scale on getting notes back to work on upsizing the Ormerod at work! This is to increase the foot print to 300mm square (with a view to go larger), use an X-Y head and potentially one of the extrusion systems without a bowden cable. Does anyone know the exact specification of stepper motor used on the early Ormerod 2 machines made by RepRapby WesBrooks - Ormerod
Interesting thread. Considering re-building my Ormerod 2 to a core x-y style machine to increase build area and this thread has allowed me to avoid a few rookie mistakes! I've seen many efforts to address accuracy or build rates of AM machines by targeting single measures, and often not following through the work to show the effects the developments would have for the end user. As a community doby WesBrooks - CoreXY Machines
Fair point. I'll have a look for some updated suppler lists. Edit - for the electronics.by WesBrooks - Reprappers
Thanks for the tips. I think I had perhaps posted a bit soon. Not quite feasible for home at the moment, but the H-Bot or CoreXY design does look good for a work project!by WesBrooks - Reprappers
After looking through the reviews on these it looks like you'd struggle to update firmware on the printers. I'll look for a UK based kit supplier I think and save a few more pennies!by WesBrooks - Reprappers
Hi All, Just had a look on ebay and I can see a few very cheap kits (<£200) on ebay now. I've built and ran an Ormerod 2 for work and have a reasonable basic mechanical / electronic / software compliance with a good measure of patience! Has any one used or had experience of the Geeetech or Tronxy kits? Thanks, Wesley.by WesBrooks - Reprappers
I just realised I may have made a slight muck up. The ABS I bought many moons ago is black, but I guess a better choice would have been white for the hot end parts?by WesBrooks - General
Thanks again I will read through those links. There a re a few mods like the lead screw for the z-axis that I'd like to get sorted at the same time. As it happens it is PTFE that is holding us back to 250C on other parts of the project.by WesBrooks - General
Thanks for the reminder on the Ormerod II forum. I'm using this printer for work based R&D so I often go many months between using it and get right out of touch with everything and have to play catch up! I do remember using your firmware though! I've altered the topic title from 'Modifying Ormerod II for High Temp Extrusion' to 'High Temp Extrusion' as I am aware there are an number of diffeby WesBrooks - General
Morning All, I'm currently searching through the internet looking for information on advised modifications in order to run high temperature plastics through the Ormerod II. If any one has any links to favourite/reliable/unbiased articles on hot ends please share a link with me. Current interests are with melt temperatures of up to 250C. There are some applications where die temperatures are arby WesBrooks - General
I'm also looking for help on trying to make the Duet binary file for upload by Bossac. I think everything is installed and working. I get the following message when I run project - build all: 14:52:30 **** Incremental Build of configuration Release for project RepRapFirmware **** make all 14:52:30 Build Finished (took 97ms) Where does the binary file go? I was also expecting the build to takby WesBrooks - Firmware - mainstream and related support
Perhaps a little premature there, moving a copy of the make.exe to the same folder as the eclipse executable seemed to do the trick. The verification only takes 93ms? How would I get a binary file version ready to move over to the Duet with the bossac.exe?by WesBrooks - Firmware - mainstream and related support
Hi All, I'm running on windows 7. Installed V2.3 from here: Trying to compile dc42's version of the firmware. Following these instructions from the 'Setup the RepRap Firmware project' section down: Build has no warnings before compliation but complains it can't find make. Should I copy the file from: C:\Program Files\Arduino\hardware\arduino\sam\system\CMSIS\Examples\cmsis_example\gcc_arm aby WesBrooks - Firmware - mainstream and related support
Thanks dc42. I've been reading around the duet since my post and think learning a little more about the extension header may cover what I need initially to break out stepper control signals. This will cover me for a while but I'm concious that I'll need to start getting my head around the Duet and other offerings sooner rather than later in order to lessen the learning curve when it's really neeby WesBrooks - Ormerod

Would there be a better choice of electronics hardware to go with if I am interested in changing aspects of it such as the stepper drivers?by WesBrooks - Ormerod
Afternoon All, I'm currently using the Ormerod 2 as an experimental rig. It is likely that in the near future I will have to modify parts of the electronics or hardware to better suit my needs. Are there any online resources that detail the deveopment of the hardware and electronics to this current point? I'd like to know why certain design choices were taken so that when I'm considering modifyby WesBrooks - Ormerod
Evening. I Just got a page with a few hyperlinks and a couple of grey buttons. I'll replace the files in the www folder of the SD card and try again tomorrow. Thanks.by WesBrooks - Ormerod
Evening! Thanks for that message, it's helped a lot. I'm going to move the printer tomorrow so will have to start from scratch on the correction but at least the next problem is solved! Is the web interface much more basic on this version or have I a little bug in my config files?by WesBrooks - Ormerod
I've seen the other thread with problems relating to home but I don't think this is a limit switch issue. If I open pronterface.exe home x, home y, and home z all looks fine. But if I home z again it steps diagonally +x +y. It will diagonally step each time. If I issue the following command it will still stide step, but after homing it all works fine: M556 S78 X0 Y0 Z0 Incidentally when is theby WesBrooks - Ormerod
