Re: HEAT BED PROBLEMS - 10 years ago

@Waitaki, heated bed MK2a, which I had once, have the same problem... At that time when I measure the resistance between the two lines it is 0.02 ohm, then I was advised to remove the copper layer by reprap members via IRC, and so I milled the backside copper and checked the resistance between the two lines, it is measured as 1.2 ohm, then I connected the power supply it worked fine "The prob

Re: HEAT BED PROBLEMS - 11 years ago

Forgot to say I am using MK2b heated bed platform which uses 24v DC too! It is good you know, faster heating ! I love 24V rather than 12V nowadays!

Re: HEAT BED PROBLEMS - 11 years ago

I got the same Problem with the RAMPS 1.4a which is manufactured and assembled completely by myself When I use first, the fuse (big yellow one MFR1100) blown away and doesn't work for a while and after few hours it started working (checked with Multimeter) it seems it uses more current, (I always use couple or more wires to solve current related issues!) Later I worked with that but it cannot pu

Re: HEAT BED PROBLEMS - 11 years ago

While testing with Multimeters have you checked the resistance of Probe, Some probes will have resistance around 0.6 ohms to 1.5 ohms some times we miscalculate this as original reading, for safety check the resistance between the probes by touching with each other while the Multimeter knob in 200ohms

Re: 24V to 12V Heater - 11 years ago

@Traumflug: Yes I have heard from a heater manufacturer saying, heaters which he supplies can work from 5V to 24V DC why I have this question is, I saw a heater became red hot when connected with 24V Dc, in other hand it works fine at 12V DC In Bang bang mode, i am afraid that the heater may not produce the constant heat with precise control which will result in Print quality!

24V to 12V Heater - 11 years ago

Hi I tried with 24V DC Power Supply, The problem is, I have 12V ceramic heater which need to work with 24V, so I thought to use a buck dc converter I measured the current in the heating element (ceramic heater) It is 6.5 Amps I could not find any buck converters that can be used for this high current Tried LM2956 a ready made one http://www.ebay.com/itm/1pcs-DC-DC-Buck-Converter-Step-Down-Module

Re: Fried Sanguinololu? I shorted pins.... - 11 years ago

I was wondering, see if you short the 12V with 5V the FTDI will blew away, so you cannot talk to your chip! I have fried my Sanguinlolu1.3a in the same way, but the story of shorting 5V and 12V is different I replaced FTDI It seems it doesn't work may be the atmega in the board fried too ??? I have a spare board so I replaced it !

Re: Need Help with heat bed reading - 11 years ago

Most firmware that is downloaded from the internet works also most people use RAMPS 1.4 as their Electronics, I could not provide the exact firmware you require because the calibration will be different for your machine moreover I am using Sanguinololu 1.3a for my Printer

Re: Need Help with heat bed reading - 11 years ago

Probably Ramps uses two heater with additional extruder ie., you can use dual extrusion using Ramps, T1 is meant for second nozzle not for bed, use this image for wiring connection

Re: Need Help with heat bed reading - 11 years ago

It is showing 0.0 degree because your thermistor is not accepted by the board, check whether you have enabled the heated bed in firmware

Re: Prusa i3 x-axis drift - 11 years ago

I suspect Limit Sensor wiring (including connectors) also check the Stepper Driver is overheating ! Over heating of stepper driver causes you missing steps. Have you provided heat sink for stepper drivers ? also try PC cooling fan to blow away the heat from the stepper Driver

Re: Extruder digging into object - 11 years ago

Hi Aegis1980 you have the calibration error in Extruder: To calibrate the Extruder 1. Take the Extruder out of the Nozzle 2. Feed the ABS or PLA 3. Extrude 50 mm or 100 mm 4. Measure the Length Extruded 5. Note down the Expected length and extruded length readings 6. Change the Extruder Steps per MM in config.h in firmware by calculating Expected steps per MM in E Here we go x is the desired st

Re: Ramps 1.4 prusa i3 Vibration only during printing - 11 years ago

Uncle_bob is correct, it may be because of Motors, need to look after the firmware speed settings Some stepper motors are manufactured with less current rating where the speed also goes down so if the speed you are using is increased, then the torque will go down, which lead to vibration!
