Today, I'm going to be talking about how you can destroy your extruder head with nothing more than a slightly greasy build plate. I did a print run a few days ago using PETG on a Prusa Mk4. PETG is slightly more difficult to print than PLA as it uses higher temperatures (240 vs 200) and it needs a satin steel sheet to print on, rather than a smooth steel plate for PLA. PETG will stick very, very well to a smooth plate, so you always use a hot (90C) textured plate to print on. Once you know that, PETG is fine to print on. Did a quick print overnight and came back to finding this lump of plastic hanging from the extruder Mmm... lovely. It was supposed to be part of a 3d guitar, but clearly went wrong as it appeared not to have stuck to the plate. It actually ended up wrapped around the bottom of the extruder and filled just about every nook and cranny and was stuck everywhere. The problem now is that the extruder surrounds are all printed in PETG so this is now one big f"£$%^&*()ing mess. Heated the nozzle up to 250C and managed to prize the above off but it was everywhere else and the heat of the nozzle wasn't enough. Tried to use a heat gun and ended up pulling most of the bottom of the extruder off as it was basically just one large lump of plastic now. You should NOT be able to see the bottom chrome bar through the extruder. The photo makes the damage look a little worse around the middle of the extruder. However you can see the nuts exposed, the linear bearings and all of this should be hidden. The next problem is that new parts are needed and can be printed. That's one great thing about Prusa is that most of the parts can be downloaded and can be thrown onto a printer. I don't believe Bambu, who make great printers BTW, can do this. Thankfully I have a second Mk4 and once I'd worked out the two parts needed, three hours of printing got me two new parts. The problem now is that you have to completely dismantle the printer head as the larger green item above is the extruder chassis that everything hangs off. <sigh>. Pretty big job. I spent a few hours yesterday gradually dismantling it and then starting the rebuild. The major issue is getting the tension on the bearings just right, which involves getting screw tension just right. I then have to put the belts on and use a tuner to get the belt tension to 82Hz. 82Hz is pretty close to E on a six string, so will try this with a cheap clip on tuner first Hope to get this done tonight, but an awful lot of effort for a print not sticking to the build plate.

I've not had to reinstall the software. nor load and presets each time I restart the pedal. I have reset the pedal deliberately as I cocked things up, but it just worked. The interface is rubbish and someone earlier suggested the librarian should be split from the pedal bit. I think that's a good idea. Indeed the iPad version doesn't have the Librarian in it which is annoying. What worries me is that you have had a lot of problems that I haven't on Windows. I haven't used it as an audio interface though. I have a crappy old Lenovo, Windows 10, with 16GB of ram but its 5-6 years old, minimum, might be older.I did nothing clever so I'm wondering what you have thats messing you up. @bnt seems far better versed than myself on this stuff, so I'll defer to him but I'm happy to help when I get back fromLondon Rob

Is this on the pedal or in the application? As @bntsaya just use the librarian section of Tonex. I set the pedals up and do everything there. However I do very little in the pedal apart from volume and gain. I'm quite simple about this stuff

The software is very very irritating. IK multimedia have made it very difficult to do anything at all. It's difficult to remember a piece of software so cumbersome to use. Then I think about the England RUFC and their Game Management System software and think I'm blessed with Tonex 😊

That's one way I use it. I'm also trying to work out how to use midi to totally control it so I can switch both units from a single foot switch. I haven't got a band to play with (sob) so it's for my personal interest. I'm back from London end of week so will try and show what I'm doing if anybody has the slightest interest

Not as far as i can remember. I have the three button version and there are loads of presets. I've just set up the first six slots for my Telecaster and the second six slots for my bass. I didn't download much from memory and having the three switch version for some 'boutique' sounds that I suspect I'll never use. I've hooked it up to Mac and Windows and whilst the interface is a pain when all want to use is the pedal, it appears that I have to have Amplitube as the authentication for Tonex. I did not have the feedback issue you had. The software has a poor interface but it does work at least for me. I think you should have all the hundreds of presets I have, that's my understanding. You should also have lots of downloads as you've brought the hardware. The free version of Tonex has a restriction of 20 downloads from memory (that's ever!). I'm away tonight so can't check anything out. However I can say that I do like the Tonex. I use the software to set it up and then ignore the laptop. I have no idea if it's accurate but it sounds great to me plugged into a Yamaha hs7 monitor. I've never played a 57 Bassman wish I could.

No, the manual is crap, it wasn't you.

That's if they would even deign to speak to you... I had a Parisian girlfriend for a while, she would often never speak to me or acknowledge me, mmm.... now that I think about it, I wonder if it was me....

I found what I think is the first pic on an older advert from Reverb from a month ago. I looked at the case marker on the right. I was going to say I'm no Rickenbacker expert but will now just say I'm no expert. The pictures look identical to me. Sadly I have no idea how to look at old sold stock on Reverb. The second pic in the sequence of two is a standard pic. Wouldn't touch this with a barge pole TBH Rob

I saw that and thought

No it doesnt pass under the strings. Camera angle makes it look it does. However the angle is quite acute.

Nah. Just spent a few evenings with it doing first aid courses, concussion (headcase) and now got safeguarding to do. We're trying to get all the coaches through it and DBS checked and it's driving me up the wall. I hate it with a vengeance. However it did come across aggressively.apologoes Rob

I doubt it. I will fight to the death that the UK RUFC Game Management System is worse than yours.
