Re: Best Capacitive Proximity Sensor for Glass Sheet on PCB Heater? - 10 years ago

When it is not triggered; 11,82V (Sensor Output) and 0,62V (Signal Output from Sensor) 11,84V (Sensor Output Reach to Ramps 1.4) and 0,92V (Signal Reach to Ramps 1.4) When it is triggered; 9,31V (Sensor Output) and 2,66V (Signal Output from Sensor) 11,97V (Sensor Output Reach to Ramps 1.4) and 3,81V (Signal Reach to Ramps 1.4)

Re: Best Capacitive Proximity Sensor for Glass Sheet on PCB Heater? - 10 years ago

When it's not triggered, it is 0.91V. Is it enough (3,80 volt) when it is triggered? Because, capacitive sensor doesn't work well everytime. I watched this video: and I use 15k and 10k resistors like below:

Hi, I use it in cartesian 3d printer type. I modified g-codes for Z-Probe with NPN Capacitive Proximity Sensor (LJC18A3-B-Z/BX). I measure capacitive sensor data from multimeter: Input: 11.64 Volt Signal: 3.80 Volt Sensor Output: 9.72 Volt Is there any problem?

Re: Edges of recengular shapes are OK, but circles are disaster - 10 years ago

QuoteDownunder35m Depending on the material and part I print the solid infill speed is between 20 and 60mm/s, normal infill again depending on the material between 30 and 100mm/s. Giving you my settings would not help as your machine is different Only a proper calibration with some test to check the max possible speeds will help you. What is the difference between solid and normal infill?

Re: Edges of recengular shapes are OK, but circles are disaster - 10 years ago

QuoteDownunder35m Ususally you get infills like that if a rectangular infill pattern is selected and he infill speed is far too high. This causes the filament to only bind to the cross sections without forming a bridge between them. Either reduce the infill speed and / or try a lower layer height. What is your infill speed? Which program do you use? Could you please give settings of the progra

Re: Edges of recengular shapes are OK, but circles are disaster - 10 years ago

Quotedc42 What hot end is that? I don't recognise it. Shouldn't there be cool air blowing over the fins? The varying temperature could mean that extrusion is jerky, which would also explain your print quality issues. I don't understand what you can say. Design of the fins are incorrect or position of them are incorrect? If you were in my place, what did you do? I want to solve printing problem,

My layer and infill problem still continues. I changed extruder holder system and hot-end temperature (I measure nozzle 220 centigrade degree and fin 245 centigrade degree from multimeter): The picture from Duet Webinterface. Heater 1 (Hot-end temp.) is not continuous as you can see. -------------------------------------------------------------------------------------------------------------

Re: Edges of recengular shapes are OK, but circles are disaster - 10 years ago

QuotePaul Wanamaker I think your primary issue is with extrusion, there are multiple indicators: - Gaps in printing - That diagonal pattern that you see, with blobbing. I believe this is caused by a slight temporary underextrusion on the previous layer, and when the next layer goes over that spot it doesn't quite have enough foundation to stick to, and so a blob forms that eventually sticks a sho

There is printing time problem. I see 53 min. for printing time, but I print this object in 2 hours. What can be the problem caused? Software or hardware? I use Duet 0.8.5 and Cura 15.04.2.

Re: Edges of recengular shapes are OK, but circles are disaster - 10 years ago

QuoteDownunder35m You have to measure what comes out of the extruder and adjust the stepping accordingly. Works best with the cold extrusion prevent disabled in the firmware as you can play back and forth without the hotend and wasting filament. Mark the filament and extrude 10mm - measure it. It is not 10mm +-0.3mm already adjust the stepping a bit. Extrude 30mm and check again. If required adju

Re: New firmware 1.08e and Duet Web Control 1.06 - 10 years ago

Hi, I am a Duet 0.8.5 user. The webinterface is very nice, congratulations! However, I want to say do you add an option for "Restart" button in webinterface. Because we must click the Emergency Stop to stop the printing when we face a problem with printing part. Then, all heaters (nozzle and heated bed) stop and temperatures decrease. "Pause" button can be used for this purpose, but pause enable
