Excited to see the progress on it! I for one would be interested in hardware kit, though I might try to see if it would be possible for me to fabricate some of the non printed pieces in my university's metal shop.
Is everything running well on the firmware side of things?
Speaking of M563, is it ok if multiple tools use F0?
Also, my fans 0, 1, and 2 are actually dedicated for the heatsink fans of my 3 extruders. Will it be a problem to use M563 P3 F0 in this case? I currently have no cooling fans on my printer.
Yes that's the longest loop time, around 18ms. What I think is happening is that the model contains a sequence of very short moves and this means that the move queue isn't long enough to hold 0.5 seconds worth of frozen moves plus enough moves for the lookahead to work in that case. The move queue on the Duet 2 series is 30 moves long AFAIR.
Increasing XY acceleration may reduce the underruns, but may itself reduce print quality.
@mwinterm said in Problem with setting working coordinate systems:
I also would like to write a generic macro to set the current WCS i.e. doing something like
G10 L20 P1 X0 Y0 Z0
without having an explicit reference to WCS1 but instead just applying it to the current WCS. For setting the tool offset this possible by just calling
G10 Z0 instead of G10 P1 Z0.
This will be supported in the next 2.02RC.
@jml said in Unwanted speed increase near corner of print:
While the top layer of a raft was being printed at 100% infill, everything was going great. But near the edge of the print when it had 8 or 9 back and forth lines to print, the speed increased gradually.
I checked the g-code as well as the preview in Simplify3D - there is no speed increase in either of them. No G1 commands with any F in them except for one line after a retraction.
Then when it got to that side of the print for the 2nd raft top layer, it did it again. I would say it reached double the speed it was supposed to be. Again, the Simplify3D preview and the actual g-code have no speed increase in it for this portion of the code either. It did not affect the quality of print - it looks like it extruded proportionally faster as well.
Has anyone ever experienced this before? And can anyone guess what caused it?
It doesn't get faster - it just appears to. I suspect you have acceleration and /or instantaneous speed change set high.
Assume for a moment that you had infinite acceleration and that you set a print speed of 50mm/sec. A 50mm long move will take 1 second. Now as you move towards the corner, the moves get shorter so take less time. A 25mm move will take 0.5 seconds. Halve it again to 12.5 mm and it'll take 0.25 seconds and so on. Each time the length shortens, the time to make it shortens too. However, in practice the only time we have infinite acceleration is when instantaneous speed change (jerk) is applied. So if you reduce the "jerk" then the print head will have to decelerate to a lower speed. Also lower acceleration will increase the time it takes to get up to full speed and slow down again. So in a nutshell, try lower jerk and/or acceleration.
@bricor said in Duet Wifi-Establishing Wifi connection requires multiple resets:
That was more of a general question and (mostly) unrelated to the issue.
What is typical in this situation, did I really mess up by buying this "deal" direct?
I have to ship the board back to the UK at my expense? (i'm in the US).
or is that a question for Duet3D.com (or is that you?)
@kwhitehouse68 if you erased the firmware you will need to use fallback procedure #3 on the documentation page you linked.
I don't have a Mac however there are instructions at the bottom of the section about how to use bossac to upload an image to the board.
@keyz182 said in Duet3D wifi for 3D printing and laser cutting/engraving:
Also, if anyone in the UK wants one of those boards mentioned on the wiki, I've got 9 of them spare - JLBPCB had 10 for $2 if ordering through EasyEDA, so I ordered extra components too.
I can send them assembled or unassembled (none are assembled currently).
Hi! I have just registered on this forum, and yes, I would like an assembled board please.
@danal and @Jacotheron Thank you for the information.
I probably just have to do it for the erase switch only since power cycling is good enough for me for resetting it.
I think I'll solder to the board since warranties were made to be voided.
I'll check with the multimeter to make sure I do it correctly (if I do decide to try it).
I'm having a very similar issue with the Maestro running 2.01. It pings and telnet works, but http is intermittent. Some times it works on power-on and sometimes it doesn't.
M122 reports that http is enabled and doesn't seem to report anything unusual.
Just to clarify, if you want to separate the printer network from your home network, the third number (octet) does not necessarily have to be different...it depends on the subnet mask. If using a 24 bit mask (255.255.255.0) then the third number must be different but the ip address ranges can be subdivided using the mask so that a 192.168.1.0 network can be divided by using more than 24 bits in the mask. So with a 25 bit mask (255.255.255.128), it becomes one network with an address range from 192.168.1.1 - 192.168.1.126 and another with a range from 192.168.1.129 - 192.168.1.254.
Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
