I think the option of skipped steps could still be the cause. you could try turning the acceleration down slightly or the power on the driver up slightly and see if the problem goes away. (alternatively the power on that stepper driver could be up very high and it could be thermal shutdown kicking in but this is less likely - see if the stepper drivers feel hot after running for a bit. cheers Tby T3P3 - Delta Machines
Hi Bret That may well work and the power certainly is not an issue, one work of caution though is that the hotend, printing PLA would normally way to be cooled at full power all the time, while blowing on the print is often controlled in a variable manner depending on what you are printing (bridges etc). I have not had issues blowing at the print all the time using PLA though. To answer the secby T3P3 - Firmware - mainstream and related support
Good news Bret Without a lot of details and investigation I cannot categorically say it would be OK it would depend on the PWM speed vs the fan coil inductance. I would experiment, starting from a very low PWM setting, and monitor the fan temperature carefully over some time (or buy a 12V fan!) Pin out wise you would need to google that, most fans I use have black and red for gnd and voltage withby T3P3 - Firmware - mainstream and related support
Hi Bret Nothing jumps out about your display settings within configuration.h that baud rate is odd though so there is a chance that there is some weird interaction going on there that I have never seen before. Cheers Tonyby T3P3 - Firmware - mainstream and related support
Hi Bret The more recent versions of Marlin should all support the Panelolu2 so its probably not that however it does not hurt to try the, now quite old, T3P3 version to rule out that as an issue (https://github.com/T3P3/Marlin) ensure you use LiquidTWI2 etc as I describe in the summary of this blog post (http://blog.think3dprint3d.com/2013/02/panelolu2.html) I guess you are doing all that if theby T3P3 - Firmware - mainstream and related support
Hi cobrageek They are not supposed to be mutually exclusive - both should work. One caveat is that the manual controls within pronterface wont allow you to override an ongoing print (ie move the axis during a print) but they will allow you to chenge the temperature of the hotend, bed and enter other G-codes (such as M220 for setting the speed). which version of Marlin are you using?

Hi All We are having a sale right now at www.think3dprint3d.com, alot of things discounted including a Duet+Duex4 bundle, Nema17 motors, belts, puleys, Panelolu2 etc. Also we have released a kit to build a mini Kossel delta printer based on Johan Rocholl's design. Just this bank holiday weekend the Discount Code: 3DSpring will give a further 5% off over and above the sale prices Have fun! Toby T3P3 - Vitamin Kit for Sale
If you can keep the Duet away from the warm temperature and replace the PLA with ABS then using a box is a very simple solution. I used that on the first mendel90 I had before going to a snazzier enclosure made of corrugated polycarbonate from B&Q. Now the Lasercut Mendel90s come with acrylic enclosures which look nice but as far as keeping the heat in work no better than the original cardboaby T3P3 - Ormerod
Dc42, Ahh you are right - never compared the datasheets before.by T3P3 - Ormerod
Dc42, not sure that the ADC is worse - rather that the sense resistors we used to be a better fit at 160C + make it a worse fit at 16C.by T3P3 - Ormerod
Just for reference the Ethernet PHY on the Duet supports MDI/MDI-X so it will work with a straight through or cross over cable.by T3P3 - Ormerod
No we dont do that one but email whoever you got it from, they should be able to help.by T3P3 - General Mendel Topics
If you already have the Panelolu2 then you can just email us to get an adaptor board for RAMPS. Cheers Tonyby T3P3 - General Mendel Topics
Hi Fraschizzato From memory when designing the Panelolu2 one of the drivers for using I2C was to reduce the number or pins used in order to make a screen for Melzi. If the Smart controller uses a direct connection for all the LCD and encoder and SD card pins then it will probably need more pins that are available on the Melzi board expansion header. The version of Marlin that RepRapPro modifiedby T3P3 - General Mendel Topics
Hi Dario It is supported by the Duet, but clearly you need the Duex4 expansion board to run more than one extruder. Like I did for the Mendel90 the hotend mount would need some modification. My Multi Extruder branch of RepRap firmware works with it already Cheers Tonyby T3P3 - Ormerod
Dave All valid points, the main advantage in my experience is the ability to reduce the size of hotend for multiple extruder setups. The water cooling is very efficient in comparison to air allowing for a relatively small cooling block with a number of closely packed nozzles. It is probably over complicating things for a "standard" single extruder setup. Cheers Tonyby T3P3 - Ormerod

which is what the Kraken is...by T3P3 - Ormerod
Hi Guys You might want to look at the e3d Kraken: Blog on printing with Duet and E3D Kraken e3d Kraken Its a water cooled monster but the theory could be scaled down to a single extruder. On the other hand it provides for future expansion. I use a small pump that used to drive a pet water fountain - you dont need a very high flow rate to keep it cool, even with all 4 nozzles hot. Cheers Tonby T3P3 - Ormerod
Hi jstck mine is attached permanently but powered through a mobile phone power brick as it required less messing about with cabling than using the +5V from the Duet or the power supply. Cheers Tonyby T3P3 - Ormerod
Hi All For your info it turns out to be very easy to setup the Duet to work with a WLAN router: Hope this is of interest! Cheers Tonyby T3P3 - Ormerod
Pull requests into the main Duet branch and then we can start with a new version number and "a" againby T3P3 - Ormerod
iamburny Great work with the web interface. I have a "feature request" is there any chance that the temperature graph window could have the option to open in a new tab, and that tab contain a graph with more detail, especially time ticks on the X axis. Messing with manual PID tuning and being able to write it up using the web interface would be great. Cheers Tonyby T3P3 - Ormerod

Hi Jeremy Ground wire for the bed fan should be onto the FAN - (marked F- on the breakout board) which is on core 12 of the ribbon cable and goes to D09 - on the RAMPS look at the wiring for the second extruder. The table on page 63 of Nophead's Mendel 90 manual for the full pinout of the ribbon cable.

Sorry for the typo above - I meant to type "hotend" (changed now) it should make more sense now. The X carriage ribbon cable has the +12V and GND on it if you have connected it as per Nophead's design, without the breakout board though I am not sure how you have wired the hotend etc into the D connectors. If that is all soldered in and insulated so you can get to the 12V+ and GND at all then anby T3P3 - Mendel90
Hey Jeremy As its meant to be attached to +12V and Gnd you can use those ports that exist on the ribbon cable breakout board. This picture should help illustrate what I mean, just ignore the bits about a second extruder: Lasercut_Mendel90_Dual_extruder_PCB_wiring.jpg Its from this blog post which also has the wiring as a table (or use Nophead's Mendel 90 Manual) dual-extruders-on-lasercut-mendeby T3P3 - Mendel90
Jens Nice build! interested to see you are going for a "normal" 200x200 heated bed with the larger mirror tile from Ikea - have you had a chance to measure the top surface temperature to see how that's working? I really how the Mendel90's parametric design make resizing it relatively easy. Cheers Tonyby T3P3 - Reprappers
