Hi dc42, I'm controlling the printer using Pronterface and not the web interface at the moment so the (more straightforward) option you've outlined can't be looked at for now. You did refer to reset/emergency stop for processing the config file. Would this need to be done each time the data on the config file is updated? if so, I'll need to try this as I've only updated the config file and thenby RepRapRaj83 - Delta Machines
Hi to everyone reading on the forum, So, a long overdue update on the commissioning of the Delta printer with Duet Electronics. @dc42 - The tooling instructions you provided were spot on, thank you. The printer axis all move as expected and tools are recognised/reacting as expected too. A few more tweaks to get the bed level and all should be ready. Or so I thought.....

Thank you dc42, I'll get these changes made to the Config.g file and update once things are working. Thanks again, Rajby RepRapRaj83 - Delta Machines
Hi dc42, Apologies in the delay getting back to you. I've attached the Config.g file and can see the temperature for the Hotend/Bed in Pronterface. I'm not using the web interface at the moment but fingers crossed this shouldn't have any impact on the mechanics. Thanks,by RepRapRaj83 - Delta Machines
Hi to everyone reading this, I've replaced my faulty endstop and switched over the wiring on the X/Y/Z axis stepper motors but I'm still having trouble with extruder/hot end. The homing and axis movement issues I previously had have been resolved following the motor wiring change, however I'm still having trouble getting the extruder/hot end to be recognised. Reviewing the G Codes now and willby RepRapRaj83 - Delta Machines
Thanks for the input dc42, not only for your response now but also for the articles you've written on your Kossel upgrade. I'll make the checks as outlined to see if the stepper motors running in the right direction. The endstops were wired correctly however my Z endstop appears to be faulty so I'll change this out before getting the changes made.

Hi to all on the forum, I hope all are well, I wondered if anyone would be able to help me in relation to getting a Rostock Delta Printer operating with Duet electronics. I've outlined the problems below along with my thoughts on what needs to be addressed in brackets. The issues relate to homing, general axis movements and switching on the hot end/extruder.

Hi to everyone on the thread/forum, I'm looking for similar advice in relation to getting electronics for a delta printer which I've nearly finished assembling. I did think that the Sanguinololu 1.3 electronics could be used to control a delta printer but I've read somewhere that a few bits in the Marlin Firmware would need to be changed. I'm leaning towards a Duet in order to get the printer ruby RepRapRaj83 - General
Hi, version 18 also compiles without any trouble.by RepRapRaj83 - Firmware - mainstream and related support
Hi to all on the forum, I have been slowly getting to grips with Sanguinololu electronics after (finally) changing over form Gen3. Sprinter has been the firmware which I intend to upload to these electrronics which will be running a Mendel (not Prusa) With regards to the firmware. I find that when sending manual extrude commands to the printer through Pronterface, the extruder moves quite fastby RepRapRaj83 - Firmware - mainstream and related support
Hi Glyn, Thanks for the information. I'm not the best electronics person out there so it will take a while for me to interpret the circuit diagram you attached. I placed a post on the electronics forum (http://forums.reprap.org/read.php?13,134236) and just updated it with some findings. With the help of anouther RepRapper (Traumflug), it was confirmed the Gen6/7 opto can be used in place of tby RepRapRaj83 - General
Hi to all, With regards to wiring up the gen6/7 style opto to a gen 3 stepper driver, there are some changes which are needed. See below. The pins on the v2.1 endstop are VCC, Sig, GND. For the Gen6/7 endstop[ the pins are Sig, GND, VDD. Therefore you cannot plug in the replacement and go. In order to run the Gen6/7 opto, you will need to change the wires around on the current connector you aby RepRapRaj83 - Controllers
Hello again Traumflug, Thanks for confirming that. I got as far as the wiring gnd,sig,vcc wires correctly it wanted to be extra sure there were no pull up resistor shenanigans involved as with mechanical endstops. As I said, I don't want to fry anything else. Thank you very much for your help. Raj.by RepRapRaj83 - Controllers
Hi Traumflug, I have found a seller of the deprecated opto, the price is more than theopto you've mentioned. I believe on the wiki page it mentions that with the correct wiring, this can be used with gen 3 electronics but it does not mention what amendments need to be made. I'm having a look to find this out. Thanks Raj.by RepRapRaj83 - Controllers
Hi to all on the forum, I've had a gen3 endstop fail on my printer. Looks like the emitter blew. I've taken a look at the wiki which said that with appropriate wiring, a gen 7 endstop can be used in place. It looks to have the same components as the 2.1 opto but I don't want to fry anything else whilst changing it over. I can't find any details on what the appropriate wiring is. can anyoneby RepRapRaj83 - General
Hi to all on the forum, Is it possible to replace just the optical sensor on an opto PCB? i have just had one blow/fry and it looks as if the infrared emitter is dead. Checks with a multimeter return a '1' compared to '0' for pins on a functioning board. Resoldering joints does nothing to solve this either. I do not think its anything to do with the opto cable either as connecting this to anotheby RepRapRaj83 - Controllers
Hi NelsonRap, That's pretty much the same response I get from my stepstick supplier. I asked for the supplier to let me know what tests were run on the drivers as there is a chance they get damaged during transit. I know that died during transit doesn't differ from dead on arrival much but at least they can be returned in an unused state. It's a bit of a catch 22 with suppliers saying they onlyby RepRapRaj83 - General
Hi, There doesn't appear to have been any shorts causes by the bridge. I tried the extruder with astepper from a different printer and it does power up and move. I put another post up to try and find out why the new stepper I put together stopped working, even though I hadn't made any modifications to the machines setup. Most likely a(nother) blown driver but a little annoying as it was workingby RepRapRaj83 - General
Hi all, Has anyone had pololu/stepstick drivers fail on their printers. Can anyone give any indication on how fragile they are and what they can/cannot tolerate. I'm not assembling in unclean conditions and the soldering iron i use has a clean tip. The solder i use is low melting point flux core to minimise heat damage/maximise clean connections. I have built circuits to control my extruder usiby RepRapRaj83 - General
Update - No it wasn't, On very close inspection i found a strand of copper wire which had fallen in between the the 644p chip and the pcb board which was causing the problem. I fishe this out with a sewing pin and the board worked. With every positive though there seems to be two negatives as my (working yesterday) extruder stepper driver circuit is now not working.

Hi to all on the forum, Could any RepRappers out the help with the following problem? I recently changed a fried extruder stepper driver connected to my gen 3 electronics. As the new stepper was 1/8th steps, I changed the firmware on the motherboard and tested it, all was well. I then tried to get a quick test print done but before I had the chance to, the motherboard stopped working. I checby RepRapRaj83 - General
Hi to all on the forum, I have been having some trouble with my A4983 pololu driven extruder. For some reason it decided to stop working mid print. The best I can get from it is a slight rocking motion which changes to a fast vibration/humming if i increase/decrease the extruder speed or turn the trimpot. placing a bigger heatsink on the board and placing the fan closer to it doesn't seem to helby RepRapRaj83 - General
Hi to all, Any ideas on why 10mm is the standard? Does PEEK lose rigidity at extruding temperature? has anyone used an 8mm thick support and had trouble? I'm asking as PEEK seems like a very sturdy material... Thanks, Rajby RepRapRaj83 - General
Hi to all on the forum, In case anyone is interested, please see attached some tweaked extruders with larger fittings for the thermal barrier. This was done as to reduce lathe work as the tip would need to be turned down at the top to fit. Big shout to Greg Frost as this is a variation of the v6 extruder he designed. These have been repaired in Netfabb so should be good to go. Thanks, Rajby RepRapRaj83 - General
Hi Komp, Sorry about the picture. Bad camera phone shot and low lighting. I changed the settings in Slic3r. The small perimeter was 20mm sec, the same as the large one. Changed this to 10mm sec and I got a much better printout of a pulley without any strings across the hole. Very little came out when reamed and the pulley hole was a tight fit on the 5mm drill bit i used. I'd attach a picture bby RepRapRaj83 - General
Hi to all on the forum, I'm getting reliable prints from my printer.......but... 1 thing is still not working out. Although it doesn't seem to cause any structural problems, the inside perimeters on any holes printed doesn't stick very well. After reaming, a lot of it comes out which is annoying as the prints overall are good. Pic attached. I am using Slic3r with PLA filament, 2 perimeters andby RepRapRaj83 - General
Hi everyone, Hope all are progressing well with their RepRap shenanigans . You may know, you may not but for those who are having trouble with their Prusa bearing guides, here's a tip which may help.

Hi to all on the forum, Would anybody be able to confirm the dimensions of the hole in which the thermal barrier is fitted on a wades extruder? I thought it was 16 mm diameter with a depth if 10 mm like on Adrians carriage but it prints out at about 13mm.
