I quite often timelapse my prints and always like to visually monitor it whilst it's in progress. I was just interested to see custom lighting rigs people have made for their Fishers to light the print as it goes. Also, whilst on the topic, does anyone know of any spare ports on the Duet Board that just constantly spits out 5V?by ByteSlinger - Fisher
Quotetml Thanks for the suggestions! I'll start by increasing the current to 1200mA and if it doesn't help, I'll take apart the hot end. When you took the hot end apart, did you find the reason why it might be more difficult for the motor to push the PLA through if the material has been left in the hot end overnight? If the filament wasn't retracted and/or the printer was powered down before theby ByteSlinger - Fisher
For anyone who hasn't seen in the other thread "Motor skipping Steps", I spent Saturday afternoon at DC42's as he very kindly spent his time looking over my Fisher and eventually getting it working. Here's a breakdown of the steps he took (quoted from the other thread): Quotedc42 I helped someone else with a similar problem this afternoon. These are the steps we took: 1.

Quotedc42 I helped someone else with a similar problem this afternoon. These are the steps we took: 1. The original filament (supplied with the machine I am told) didn't extrude cleanly, but formed a glob attached to the nozzle. We switched to a roll of eSun PLA I had. 2. Dismantled the hot end, unscrewed the nozzle from the heatsink, then screwed it back in but with thermal transfer compound oby ByteSlinger - Fisher
This looks very similar to what I'm getting but with the extruder in the original place.by ByteSlinger - Fisher
QuoteDADIY You seem to have a lot more plastic being extruded than I do on my fisher which makes me wonder if you are over extruding. If I use the extrude button too much then my motor will crunch when too much pressure of filament builds up, the side affect of over extrusion is that you can clog up the extruder. I've just checked and it's extruding perfectly to the mm (Just to check, the mmby ByteSlinger - Fisher
Quotedc42 Sounds like you need to update the files in your SD card /www folder to DuetWebControl 1.08. Get them from chrishamm's github repo, or from the SD Image folder in my github repo where you downloaded the firmware. There should be no need to update config.g or other files on /sys. Bang on the money! Thanks for your help!by ByteSlinger - Fisher
Has anyone had issues with their hot end not cooling enough, causing blockages after 5-10 minutes printing? If so, how did you get around it?by ByteSlinger - Fisher
I've updated my board to RepRapFirmware-1.09r-dc42.bin but now the web interface is all but useless so I'm guessing I need to update my config file, however can't find one allocated for this firmware. Would someone be able to link me to an SD image for this firmware on a fisher? Thanksby ByteSlinger - Fisher
I'm finding it's either too tight and prevents the motor from driving the filament, or it's too and doesn't put enough pressure on it to allow the motor to push it. If I do find the sweet spot, it works momentarily but it just loosens itself. Has anyone had this or know of a good solution?by ByteSlinger - Fisher
OK, after just one print the issue has returned. I'm now thinking it could actually be something to do with the Idler Lever Any ideas? Is it known to be a bad design on this printer? If so, are there any recommended fixes/solutions?by ByteSlinger - Fisher
Problem Solved!! So ended up replacing the motor. Solved the issue! Thanks everyone for all your help though! Really appreciated!by ByteSlinger - Fisher
Quotebgkdavis As Ive already said, I dont recommended the traxxas, they are a bad fit, use mugen seiki they are much bettter, see my original thread for the part details. Btw just checked the details and I made a mistake, the traxxas were not the sloppy ones, they were one of those that are way too tight, they are used on a 5.8mm ball, you could possibly use them with the supplied balls, but thaby ByteSlinger - Fisher
QuoteDADIY You can download the slic3r profile for the Fisher from the git hub site - Alternatively most slicers write comments in the .g (or .gcode) file which show which settings were used. For example with the robot.g file goto line 32125 and you'll see all the settings that were used and how much filament is needed. Brilliant! Thanks. I actually found the git hub one later the night I posby ByteSlinger - Fisher
QuoteDADIY Might be worth checking that the filament you want to try doesn't wear out nozzles too quickly, I'm told that some filament like carbon fiber will wear the nozzle diameter quite quickly and the quick set nozzles are in short supply (although emakershop has some at the moment.) I have heard this and thought it was a little worrying. I've just invested in a couple of spar nozzels fromby ByteSlinger - Fisher
QuoteDADIY Are you trying to extrude too much, you might need to set the extrude amount down to 1 or 5 if you're any higher then the motor can struggle. Also try increasing the temperature a little 190 may be a little low depending on the filament your using. Nope, definitely not trying to extrude too much. Tried every combination of speed and amount and makes no difference I'm afraid. As forby ByteSlinger - Fisher
I ended up going for Carbon arms myself too. Before even finishing building my printer I'd managed to snap one of the arms, conveniently, the day after RepRapPro ceased trading. From what I'd read, carbon was the way to go anyway as helped improve stability and reduced chances of future breaks. I'm very happy how solid it is now I swapped them over!by ByteSlinger - Fisher
Took it all the way up to 220 and no changeby ByteSlinger - Fisher
Quotedougal1957 QuoteByteSlinger Quotedc42 One possibility is that you have a partially failed driver chip such that one of the two motor phases can only be energised in one direction.

I finished my Fisher earlier this week and was VERY happy with the quality of the robot print I did as my first print. However, today I plugged it in and went to print my second model. This time however, problems have struck! The extruder motor is struggling, drastically! With the motor powered off (and the hot end up to 190) I can extrude and retract by hand with absolutely no problems. Withby ByteSlinger - Fisher
Or alternatively, what are your recommended settings?by ByteSlinger - Fisher
The robot model that comes with the Fisher for initial test printing, does anyone know what the slicer config settings were for that?by ByteSlinger - Fisher
Has anyone tried printing either bronze or wood filament with their Fisher? I'm very interested in trying out both.by ByteSlinger - Fisher

I'm on the Hot-End test stage of my Fisher setup and when I set the hot end to heat up to 190 it went up from room temp to around 145 very quickly. However, when it hit around that area, the temperature just began to drop again. I had initially thought that maybe something got too hot and un-soldered itself but had a quick glance at the hot-end and can't see any sort of damage or anything out ofby ByteSlinger - Fisher
