Re: Not very impressed with Smoothie

My mistake, 626pilot was indeed talking about the hot end heater connector. I've never had any worries with the hot end heater terminal blocks on the 0.8.5 being strong enough. You can always hold the terminal block as you tighten the screw if you are worried. However, along with other users, I have...

Re: Not very impressed with Smoothie

626pilot, if your Duet has the small bed heater connector then it must be the older version 0.6 board. The 0.8.5 board has a much larger connector, same as the Duet WiFi. I guess you haven't looked at the RepRapFirmware source tree for a while. It isn't as flat as it used to be and I am gradually re...

Re: EzStruder Over Heating With Duet

If the extruder motors are rated at 1.5A then I suggest you set the current to about 1.3A to that they run cooler. You can put a command to turn the unused extruder motor off in the tfree#.g tool change file, where # is the tool number. I don't recommend using I0 in the M906 command unless you reall...

Re: Best Tower Rotation Setting Yet

Have you tried plugging the height errors into my delta calibration calculator at http://www.escher3d.com and letting it work out the tower angles that give you the least sum of the squares of the height errors?

Re: EzStruder Over Heating With Duet

1. What is the rated current of the stepper motor? Is there a part number label on the motor that would help you to look it up? Try turning the current down to 80% of the rated current.

2. You can use M18 to turn motors off selectively, see http://reprap.org/wiki/Gcodes#M18:_Disa ... per_motors. For example, M18 E0:1

Re: My machines

Sounds good! I have a comment on the UPS. The Duet WiFi has on-board power monitoring, and this was included so that we can implement suspend/resume. The idea is that you use a small UPS or SLA battery or even a capacitor bank to provide enough power to park the machine and save the current state wh...

Delta printers using the Duet WiFi

About 40 pre-production Duet WiFi boards have been shipped, and a number of people have been putting them into delta printers. Four of them (including mine) are described at m. The pre-order period for the Duet WiFi was due to end by now, but has been extended to 3 August because we have a few board...

I haven't tried it, but I would expect it to work very well. The sensor will still see the surface reflection, but you won't get a reflection from the back, which is good.

Re: TMC2100 vs. TMC2660

The TMC2100 and TMC2660 both support microstep interpolation, for example you can send step pulses at the 1/16 rate and the chip will interpolate to 1/256. This is what Trinamic calls 'microplyer'. So both will make a printer much quieter, especially during long straight moves for which the interpol...

Re: Duet setup - instructions in progress

This is getting very strange. Here are a few more suggestions: 1. With power off, disconnect one of the motors, and check for continuity between the correct pins of the motor cable where it plugs into the Duet. If we label the pins 1 2 3 4 in order, there should be continuity between pins 1 and 2, a...

Re: Duet setup - instructions in progress

I suggest you start by testing the motors individually. Place the carriages about half.way up the towers, then power the printer on. Connect to it using the web interface or USB or PanelDue. Send G91 to put it in relative coordinates mode. Then send G1 S2 X10 F500. This should move the X carriage up...

Since Duet is open hardware, their SPI protocol (which appears to be simple Gcode) should be easily portable to any microcontroller with an SPI port. That being said, it should be pretty simple to port their ESP8266 webserver to any other CPU with any other outward facing network connection. I just...

Re: Duet WiFi details published and pre-order window open

Extra pads to break out the unused ESP8266 pins have already been suggested on the Duet WiFi forum, and will be included on the production boards if we can find room for them. The pins we are not using are GPIO2, GPIO5, GPIO16 and ADC.

Re: PT100 reading 2000°

The console window of PanelDue should show any error messages. If you are trying to heat the hot end to 260C or more then you will need a M143 command in config.g to increase the maximum allowed hot end temperature.
