Printing issues ...
Quotejay_s
I've powered mine with 24v and had the issue of it taking a while to connect on the network. With RRF3, I don't get that issue. Once loaded it works fine.
It may need @sdavi to come in as I don't know what changes have been made in RRF between version 2 and 3.
@MKSA
If you like DWC, might be another reason to look at upgrading to RRF3.
Obviously it is not a power issue !
Anyway, m

Sorry I haven't replied earlier.
I had this happen with one of my boards with it taking forever to show DWC.
You could try what sinned recommended and statically assign an IP address and see if that fixes the issue. I upgraded to RRF 3 (to match the rest of my machines) and the issue went away.
I don't think it's related to speed as the issue doesn't exist on RRF 3.
I suggest

I installed DWC, tried different browsers, ended up with Chrome ( I was sure it works with Java) could see that definitely there was something going on but nothing just the rotating arrow and no timeout.
After different attempts, I gave up and went to something else while it was still "running".
Then big surprise after about FIVE if not more minutes, I got the Web control panel ??????

Well, respect to Makerbase -- they managed to build a $20 closed loop stepper motor. They didn't steal anything, their product is open source and is based on another open source product (and they acknowledged the original creator).
Open source like in: copy an open hardware design, use cheap (aka slave) labor and parts to sell it making an immediate profit (no development cost, marketi

Ok, so I got an answer directly from Makerbase. It turns out that both motors use Allegro's A1333LLETR-T magnetic encoder. In fact, previously they were using AD5047D but because the supply was very unstable they changed it to A1333LLETR-T.
They changed because it is cheaper. Do a search about this product and how dishonest these guys are, stealing others work !

I currently stay with RRF 2 as it is "frozen" and currently does what I need. Will eventually move to RRF 3, just I don't want to get confused by other issues
No problem, just wanted to make sure you were fully informed.
I'm currently running the latest 3.01 RC1 on a printer mainly without issue.
I'm eagerly awaiting your feedback as to whether it works or not.

Indeed, 7mm is quite big but I decided to use a magnet instead of an optical disk that would be bigger, fragile and subject to dirt.
Not easy to find multi pole radially magnetized magnets.The tore magnet I use (taken from a main timer clock "motor") has only 6 poles but is so small (9mm diam) I could fit it to my extruder idler (14mm).
The output I get is a square wave that corresponds

As previously stated, no need for such compexity when using a properly made hobbwheel with sharp teeth and of a bigger diameter than the common ones (most are just regular small module gear).
I saw the hobbgear you made and althoguh the teeth seem sharp, the diam is too small and therefore not that many teeth biting the filament. Stainless steel is not the best material either. Personally I use

Hi @sdavi, I've just noticed that some of your RRF repos are currently marked as archived. I hope that doesn't mean you no longer plan to update them as that would be a great pity.
They have been archived as I don't plan to do any further updates at this time. I've left everything there on GitHub so others can fork it and can merge in changes from the official RRF rep

OK, found a usable pin on the MKS Sbase, the one used for a 4th thermistor (???) as none of the endstop are interrupt capable. Got it to work. It just adds 2 g to my extruder and a nice flashing blue LED

@DC42
Thanks, will do some reading.
Note currently I am just making this sensor and integrating it in my extruder idler.
I found a small radially magnetised tore and wanted to try it. I get 6 pulses per turn which represents about 7mm of filament per pulse.

Indeed, makes sense if you want to be able to pause then resume a print but if you want to just raise an alarm then abort/stop, it

There is no reason that I'm aware of that it wouldn't work, but I haven't seen any reports of anyone trying one either.
By all means try it but if it doesn't work, I would suggest looking at using RRF3 instead of RRF2.
This version is pretty much frozen now and won't have any further development carried out.
If you're using this with an MKS Sbase, I take it you are using the ethernet

Does this RRF version support this function and/or has someone used/tested it with a pulse generating sensor (https://duet3d.dozuki.com/Wiki/Duet3dFilamentMonitor_RotatingMagnetVersion#Section_Technical_details).
I am using a digital Hall sensor 3144 and a magnet mounted on my extruder idler giving 6 pulses per turn (about one pulse per 7mm of filament.) and plan to connect it to one of the free

Misalignment and thermal expansion are compensated by mounting the rails, etc with plastic printed parts that are not very sturdy. This can be seen on the machine.
Fact is, the better the parts, the design you use, the more you have to know about proper rail mounting.
Cheap chinese rails have certainly enough play or are soft enough to prevent binding

Well that is one issue with the missing PFTE, although it never shipped with any PFTE tubing. The other issue is the heat break I have never gets narrow. I was thinking of buying the e3d lite6 but migh just get the e3d V6 and be done.. too many issues with clones
A full metal is the way to go BUT it must be of good quality as poor surface finish and/or dimension will also lead to si

Your last picture shows the problem. This hot end has a PTFE liner that doesn't go far enough, leaving a gap or is missing.

For the extruder, I like the idea of using the springiness of the plastic arm to replace the spring and hinge. I often use that too. On the other hand, to build the machine frame with 3D printed parts may be a nice exercise but not very practical.

Why people keep asking opinion on computer renderings when it is obvious they didn't read all the other similar inquiries (most never materialize btw), making the same mistakes, calling for the same remarks, again and again ????
And of course read about the few working machines.

Do you need these fans, sounds like your talking part cooling.
Yes, they are the part cooling fans.
I guess the best short term solution is socks.
I like the Repetier firmware solution, but that involves another learning curve.
To fully isolate the hotend, just leaving the nozzle free of course, is not a short term solution, it is the way to do.
