Re: Heated bed power requirements for new design - 7 years ago
QuoteMechaBits I wonder if a cheap MK3 under your plate would be enough, Today i bought a 250mm x 260mm 8mm thick aluminum from a local supplier. It was cheap but on my way to home i got terrified with the possiblity the heater will be unable to heat up this mass. I intend to take to to the mill and do it from 8mm->6mm but i concern about the heater. It is a mk3b heater with both 24/12v suppby Gaou - General

Re: Duet compatible steppers - 7 years ago
i am ready to purchase the steppers and i just wanted to be sure once more . So with these steppers the duet would work without the need of modifications either on software ( firmware ) or the hardware, isn't it David ?by Gaou - Stepper Motors, Servo Motors, DC Motors
Re: I'm building n enclosure for my Printer, so I have some quick questions - 7 years ago
Quotedc42 Depending on what electronics and firmware you use, you may be able to assign one of the heater/thermistor channels in the electronics to the chamber heater, with standard PID or bang-bang control, and use the M141 gcode command to set the chamber temperature. You can use a DC-AC SSR to control the mains-voltage heater from the output of the electronics. sorry for hijacking another thby Gaou - General
Re: RepRapPro closing down - 7 years ago
Quotedroftarts Hi everyone I should also point out that, while I was one of the few 'public-facing' members of the RRP team, there were more of us, and I feel equally badly that they lost their jobs at the same time as me; Joe (who worked for RRP for even longer than me, in production, mainly packing kits), Tom (production, made all the wiring looms and packed kits) and Chris (junior mechanicalby Gaou - Ormerod

Just saw this post. Ian i am very sorry to hear the news. I think and wish on the other hand that u ll find ur way ( if you didn't do already) . You helped me a lot with my mendel and ur knowledge and speed are admirable. About the nozzle guys my personal opinion is that it is something that can be done easy if you have the tools.

did you wrote them down ? they will be open untill 15/01/2016. Also did you looked at the documentation page. There are some good instructions about the extruder but then again i cannot understand what are these parts for ? Where are you located ?by Gaou - General Mendel Topics

Re: Duet compatible steppers - 7 years ago
no its not too late but what do you mean by that ? what difference would it make if i had 0.9 deggre steppers ? is it better resolution or more than this ? I am a newbie at 3d printing and i dont have the mechanical and electronics knowledge to think of changes like this . it seems an everest to me to go from 1.8 to 0.9 but if you say it is worth then i have to consider it .by Gaou - Stepper Motors, Servo Motors, DC Motors
Re: Duet compatible steppers - 7 years ago
Quotedc42 You have the specifications of the motors supplied by RepRapPro wrong. See for the correct spec. This motor is a close match. For the Duet (as with most other 3D printer electronics), you should choose motors with rated currents in the range 1.3 to 1.7A. thanks a lot . i will order 5 of them .by Gaou - Stepper Motors, Servo Motors, DC Motors
Duet compatible steppers - 7 years ago
Guys i was on my way to make a new 3d printer like the one ( mendel ) i have bought from rpp. Some days ago i was asking about the ramps as i needed a board for contrtolling the printer but rpp came with a big offer replying to one of my many mails and so i bought a second duet pcb. The problem is that rpp closed it's shop so i am out there looking for some steppers. The steppers that rpp mendelby Gaou - Stepper Motors, Servo Motors, DC Motors

Re: Extruder gear assembly directions-mendel 3 - 7 years ago
i am not aware of any update on the mendel but if ur mendel is what i got ( got it on april or may) then i cant understand what these parts are for . I am sure that rpp didn't see the photos i jjust saw. Send them this photo and i think you ll sort it out. ?by Gaou - General Mendel Topics
Re: Upgrading melzi board to a duet board, help please - 7 years ago
in my mendel duet is controlling 1 Y axis switch 1 infrared sensor for X and Z homing . it also controls the bed and steppers and the hotend....! So most of them i imagine are the same ( steppers bed and hotend ) . just look the type of the belt and get ready for some hardware changes to fit the sensor and switch ( if they are differents ).

Re: Reprap Mendel monocolor - problem with square dimension - 7 years ago
if you bought this from reprapro there is a file in the card ( microsd) that you have to print to get the proper x-y-z scale . Here reprapro describes what you have to do . https://reprappro.com/documentation/commissioning-introduction/printing-duet/. Do it and then you ll be alright i think.by Gaou - Printing
Re: Reprap Mendel monocolor - problem with square dimension - 7 years ago
it is ABS as the bed temp is also high. Anyway i think that you are measuring the corners that expands a little. Check ur corners first . Is this one of ur first prints with the printer ? If so did you print the test with the xyz ?by Gaou - Printing
Re: Z axis 'thunking' (sticking?) - 7 years ago
this problem indicates that something is not parallel or cornered 90degrees. usually the problem is the shafts on the z axis. try mesure them on the top and at the bottom. The m5 has nothing to do with it. As it is happening only down at the prints it is telling you that the problem is down. So measure them to make sure everything are set up alright .by Gaou - General Mendel Topics

Alternative to kapton tape. - 7 years ago
I want to share my last update concernng the bed and the kapton tape. From the very begging i didn't like the kapton solution at all. First it was an expensive solution as you have to replace the kapton every few prints. Secondly i didn't like it because i did't have the ability to attach the capton well and i had bubbles of air or double kapton on some spots. So i deccided to replace my 3mm glasby Gaou - Safety & Best Practices
Re: Cleaning the hot end on the fly - 7 years ago
That is the method that i am using . One day by mistake i retracted at high speed and i saw that this worked too. Some days ago i saw in a youtube a video saying that you have to retract at high speed and to tell you the truth i confused....! Anyway for now i am retracting at low speeds and it seems to work pretty well.by Gaou - Safety & Best Practices
Re: Wishing to buy a ramps but i am afraid. - 7 years ago
Quotedc42 [email protected] Quotedc42You can get a Duet for $50. For euro 37,- (~$41) you can buy a Ramps & 2004 LCD Controller & MEGA 2560 r3 and 5 x A4988 Drivers and get free shipping. Even if your 37 euro RAMPS board doesn't suffer from the problems that some Chinese RAMPS boards do, I think the extra $9 + shipping is well worth it for the Ethernet interface supporting DuetWebControlby Gaou - RAMPS Electronics
Re: Wishing to buy a ramps but i am afraid. - 7 years ago
Thanks DC42 for ur cleared and helpfull answer. I just looked what you have told me . But one more question . If there is something bad on a board is it really hard for me to replace - upgrade this part?

Guys i need some advice as i want to build me second printer. My first one is a mendel from rpp and it was easy to build and work with . Plus the duet board with the proterface and network frindly support is something that make my life easy. But the duet is expensive comparing to what i can find on the net ( ramps. ) So i would like to ask some things. First i see many ramps boards. Are allby Gaou - RAMPS Electronics
Re: somethings wrong.. electronics maybe? - 7 years ago
man i just assume the 12 volts for ur heatbed . I dont want you to do any damage to ur printer relying on my lack of knowledge. When i am trying to test something that work on dc i am starting on the safe side . That means i am starting giving low power with low amperage. Imagine that a 12v device in my personal opinion wont get damage if you give 6-8 volts. The worst thing is that the device wonby Gaou - General Mendel Topics
Re: somethings wrong.. electronics maybe? - 7 years ago
untill someone with knowledge to ur printer answer why dont you try with and external 12v power supply to see if the bed is working ( probably it does ) . So then you would be focus on the board or the software . just connect the heatbed for a few seconds to a 12v source.by Gaou - General Mendel Topics
Re: extrusion problems help - 7 years ago
another thing i have notice today is that the wet filament doesnt help either . probably the bubbles from boiling inside the hotend is something that requires extreme force do be extracted as the steam usually goes up against the filament that tends to go down ...! so for my next steps i ll dry every filament before printing to saw if that helps. i couldn't imagine that it would be so tough .by Gaou - General Mendel Topics
