3D Printers / Re: CZ-1 2.0: problems, calibration and printing, part2
« Last post by MEgg on May 27, 2018, 05:23:38 PM »
hi meg got few thoughts  but before what
filament brand.
print speed
layer height
Temp
 temp wise print looks molten in places (those peek jheads flows pla well enough around the 180C Mk
 thinking about the box and step in the hull, when the print cooling kicking in..... continued in the SB

I think the filament was a black PLA from Honeycomb from the manufacturer:
http://construction-zone.de/produkt/honeycomb-filaments-black-pearl-pla-1-75mm/

I attach the slic3r config that I used and the .../RepetierHost/composition.gcode that seems to be generated by slic3r.
repetierhost says as print speed "100".

3D Printers / 3DBenchy boat
« Last post by MEgg on May 27, 2018, 02:28:59 PM »
After some time I found time to recalibrate the printer.
My fault: I tightened the screws of the heatbed to hard and at 2 screws the washers were missing which made the nut press into the wood of the base.
This lead to the issue that I described before were the heatbed seemed to be uneven.
A metal ring would probably be better here to fix the heatbed at the bottom.

Anyway, I was able to print the 3D benchy boat: https://www.thingiverse.com/thing:763622 :

The skirt was too near to the print:

How does the weight compare to the plastic one?
just something I never compared,  wasn't overly weighty that I had concern with, think it be just fine in a direct drive system, thou I think if  I was to go back to a direct drive with a prusa i3 build, I aim for a titan aero ( ali link to an Aero) https://tinyurl.com/y855t7fu upgrade and experiment with a pancake stepper to reduce overall weight on the X carriage.

3D Printing / UConduit H-Bot printer design
« Last post by KingBeetle on May 26, 2018, 02:10:38 PM »
I came across this design for an H-Bot 3D printer that utilizes inexpensive EMT thin wall electrical conduit for the frame, and wondered if anyone here has ever built or even seen one?



https://www.thingiverse.com/thing:102972
http://reprap.org/wiki/Uconduit
https://github.com/iquizzle/uconduit

It looks like it would be really solid while still remaining inexpensive to build. All of the information is four to five years old though and it doesn't look like any further development has occurred. There are only a handful of videos on YouTube, and several of them are the original developer's videos. It seems as if the design never really "took off", although I don't see any reason why not.

How does the weight compare to the plastic one?  Would it be suitable for direct drive applications, or would the weight still favor a plastic housing, even with a pancake stepper?

I ordered one of these 5V inductive sensors a couple of weeks ago to play with; I haven't received it yet.  My printed build is still a good month away from being complete, so I won't be able to test it out until then, but I will certainly let everyone know how well it works out.

 am not completely sure but i do think those two little white boxes are SMD fuses, if they are it would have been nice to been remover-able,,,

dont worry to much about burning the house down!!. (ALWAYS >:D FEAR IT)   two most common errors that lead to fire  are setting a bad PID to the heaters or poor wiring connections.

              As for the switches yea inductive/capacitive sensors?  I suspect the onboard 12V source aint grounded to the circuit? A vulcan guess so far... OR there a onboard resistor issue that came over from the mks gen series. seen work around for the mks gen board on youtube ( just aint keen  taking an iron too the board just yet and the mechanical switches work just fine.

Thanks for the welcome and the quick response!

nice little board  for a budget build, I cant  really complain about  the board although am not having much success so far with proximity switches...
When you say proximity switches, are you referring to actual physical switches like the 3D Touch, or inductive/capacitive sensors?  Regardless, what sort of issues are you having?

Quote
as for 24V think you be the first. most here are 12v so some of us be interested to see how that works out for you.
The major factor in my decision to go with 24V was the extra degree of safety when powering the heated bed (half the current for the same load at 12V) and the potential to avoid skipped steps at higher speeds. 

My build is extremely low budget and I have purchased the absolute cheapest steppers I could find on AliExpress that still claimed to meet the minimum RepRap specs.  I'm hoping that by using 24V I can assure myself a little wider margin for error and perhaps make up for the potentially optimistic specs on the steppers.

I have kind of applied the same logic to the power supply - I figure if I purchase a PSU rated at 360W and it's only capable (or safe!) supporting loads up to about 250W, I have a safety margin built in.

I would really like to avoid burning down my house if I can.  ;)
Which actually reminds me - You made mention in your review of the board that you were concerned about the lack of fuses - Certainly there is SOME sort of short protection on the board?

Welcome to RobotRebels KingBeetle,
 am playing with the gen l nice little board  for a budget build, I cant  really complain about  the board although am not having much success so far with proximity switches... but apart from that  its still a good choice.

Quote
Are there any major differences between the two? 
             main differences I see are the mosfet for the bed is larger on the mks gen series and the glaring layout change,,, am not 100% here but I recall the mks gen uses a four layer circuit board and the gen L a two layer ... and thats about it for me 

Quote
Any downsides to the board I am overlooking or that y'all might have encountered through use?
apart from the proxi switches giving me attitude I dont see no downsides, if all you doing is a basic printer. (if you gonna tinker you could out grow the board sooner rather than later and if you are gonna tinker and add things like ABL, heat chamber diamond hotend etc then have a peek at the mks RUMBA, its bit out of budget but it be the last 8 bit you buy.  ;D

Quote
I plan to run the board at 24V with a 360W PSU and use an external MOSFET board for the bed heater.
good call on the external bed controller/mosfet I have no regrets using them. as for 24V think you be the first.
      most here are 12v so some of us be interested to see how that works out for you.
