@t3p3tony said in An extruder to turn a spool:
@deckingman nice write up. With 5 extrucers you are always coming up against stuff that most other people don't have to worry about (like changing the middle spool of 3!)
Thanks Tony. And exactly so. For most people changing a reel of filament is relatively quick and painless job. Changing the middle spool of 3 is one thing but when I swap from say a Diamond 3 colour to a Diamond 5 colour, I have to unload 3 spools, then load up 5 spools so it's a bit of major operation. Less painful than it used to be now though.....
@lordfus said in PanelDue connecting but not fully working:
Thank you that helped. It is now working.
Cool. Remember though that @dc42 hasn't approved those changes yet so when he releases his official firmware you should upgrade immediately, assuming he accepts the changes that is.

The projects is linked here on EasyEDA.
Excellent project & write-up, @keyz182! Thanks for sharing
Could you please provide more info (& pics) regarding the laser you're using with this module? (I might give it a go myself and haven't worked with lasers before so any pointer would be helpful).
This is the laser I'm using. It appears to be using the same control board as the Eleksmaker laser modules that are all over Aliexpress and similar.
They're pretty simple boards, they take GND, +12V and PWM. They have a button on them, when off, the laser is on, but in very low power, so good for lining up parts, focusing, and I generally leave the switch in this position when not in use. When on, the laser is in PWM mode where it's intensity is PWM controlled, from off up to full power.
If you're getting one, be sure to check that it's a PWM laser, and buy safety glasses! I also got some transparent safety acrylic that filters out the lasers wavelength which I'm going to try to either enclose, or somehow shield the laser with for extra safety.
And perhaps say a bit more about what you're using the laser for? is it for etching/cutting acrylic and the like or something totally different?
I only have a 2.5w module, so plenty of etching, but limited in cutting - card, paper, thin/light wood, very thin opaque acrylic (or a lot of passes - ~16 passes at 3mm/s on some 3mm thick stuff I tried yesterday). Also remember that this is a visible light wavelength laser, so if you can see through it, the laser will "see" through it too (unless, as mentioned above, it filters that particular wavelength).
I'm trying/failing to get into leather work (wallets, belts and the like), so hoping to use the laser to cut templates and etch logos/designs/etc.

@dc42 I don't think it has a fan due to the efficiency. Time will tell.
If it's 92% efficient at 500W output, then it has to get rid of 40W of heat. It will definitely have a fan.
Hi, thanks for your reply the pancake Motors rated at 1 amp 3.50 volts will be used as..... I would love to tell you but I, I'm not ready to put it out on an open forum as yet if you'd like to know my idea send me your email address and I'll tell you my full plans for this project. Again thank you for the reply
I also agree the new version should have native SSL, but for everyone else a good and relatively easy guide and a Pi Zero W (which only cost a few bucks) will work.
I have now written a guide for the Proxy part, the camera section will come slightly later, but it is really simple to install (only real requirement is to run it on a different port than the proxy - I had issues when they were on the same port).
Any further advice, questions etc can be posted to the instructable or my other thread here, linked to above. I will try to help anyone, but usually a Google Search can also help (in essence my guide is simply a compilation of information found on a whole lot of websites, added in a logical order for this specific task).
The resistor is provided to help you test the PT100 board. If you connect it between the middle 2 terminals as in your photo in place of a 2-wire PT100, it should give a reading of 0C. It is not used in normal operation.
First check whether the Enable signal is working properly. When you power up the Duet, the motors should be un-powered and therefore free to move. When you try to home them, or to jog them (with M564 H0 in config.g or sent first to allow movement before homing), they should be powered up and no longer be free to move. If you find they are locked to start with and become free when you try to move them, then change R1 to R0 in your M569 commands for the external drivers.
Thanks for the quick reply dc42! Yes the expansion board has TMC2224's on them.
Awesome, no problems! I will follow up with M3D and see if they have any firmware builds they are happy to provide for testing.
edit: I am in no rush currently for the extra drivers as it is only controlling my second extruder currentl and can make do without for now.
I use belts to lift the Z axis in my printer. I solved the bed-drop-on-power-off problem by installing a worm gear drive. If the gear ratio is sufficient (and/or the pitch of the teeth is right), the mechanism is irreversible and no brakes are needed to hold the bed.
My printer's bed assembly weighs about 3.5 kg and does not move unless the motor tells it to move.
Thanks, that did the trick! I'm sorry, I misunderstood the documentation on the gcode page (it states "(was E3 Endstop on the expansion header)"). I can see now after looking at the pinout table how I incorrectly interpreted that.
@masock said in Duet Communicating with Other Boards:
@SnowCrash I would be interested in collaborating if there is some way I could be of benefit.
I was planning to PM you, but it seems like the forum's interface doesn't support that function (!?)
Anyway, I figured I'll respond here as you're probably following this thread. First, sorry for the delay (got called on an urgent project that required a massive time investment).
Second, I have a cheeky idea about interfacing with the Duet that I'd like to test out which might save me a lot of work on the planned expansion board. I'll try it out and report back with the results in case it might be helpful for your project too.
In the meantime, if you manage to make progress on your side, do post your findings
Okay David, now I'm following you. Thank you for the info. It's not a big deal I just wanted to make sure I didn't miss something.
The new firmware is working great! I'm running 20 out of 24 hours per day for the next 10 days with the IDEX ditto printing. Thank you for all the amazing work you guys do with the Duet!
@phaedrux it deploys it automatically now. the only thing that bothers me, as i said, is the pin popping back out immediately after triggering instead of staying inside while homing
the pin NOT staying out while moving to next probe point,
but as you said, that seems to be normal behaviour
Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
