Re: Finetunen corexy - 8 years ago

- voor PLA heb je geen heatbed nodig - afstand tussen printbed en nozzle zo klein mogelijk maar niet kleiner dan de "platheid" van je heatbed, zodat je niet op 1 plek netjes net boven het bed zit en ergens anders vol het heatbed ingaat. - slic3r heeft een verhaal geschreven over de eerste laag en waar die het beste aan voldoen. hoogte=nozzle, width gelijk aan 2 x nozzle.

Re: Filament twists and leaks out - 8 years ago

That's normal, when the filament is pushed into the hotend a pressure will build up and the only escape is the nozzle. Therefor while printing you will set the retract to solve the oozing.

@24volt that driver will run very hot. Setting the reference voltage is harder to do.

Re: Corners on Circles - 8 years ago

I think it's under extruding now but if this it the first layer then there is also an issue with the distance between the nozzle and bed. As far as I can guess the nozzle is so far above the bed that the plastic doesn't stick to the bed and the nozzle will drag the plastic away from the place where it first deposited it.

Re: Piezoelectric disks for Z contact detect and bed levelling - 8 years ago

can you include the coordinates of the sensors in the table/image? Is there a relation between distance from the sensor and the point where the data is inconsistent?

Re: Finetunen corexy - 8 years ago

Quotegforce1 Laagdikte moet je apart instellen, je hebt hem nu op 0.4 mm staan. Richtlijn voor de maximale laagdikte is 80% van je nozzle diameter. Dus maximaal 0.32 mm. inderdaad maar dan ook rekening houden met de z-axis resolutie zodat er geen opeenstapeling van afrondingsfouten optreed.

Quote19roland70mij lijkt (denk ik) dat ik meer lagen moet printen voor een gladde zijkant. Euh...een gladde zijkant is eigenlijk onmogelijk maar meer info inclusief wat microscope plaatjes oa hier Let wel zodra je ergens in de 0.05mm laag dikte of lager komt dan is zelfs een simpel vierkantje al meerderen uren printen.

Re: Building P3Steel - Steppers will not move - 8 years ago

using the ramps test code will allow testing a single stepper. Just make sure about the orientation and the reference voltage

Re: RAMPS FD with robotarm - 8 years ago

Have a look at the pololu link. The motor connector must be connected to the a1,a2,b1,b3 pins on the driver. The power supply you connect to VMOT and GND. Two pins from the DUE you connect to the STEP en DIR and the 3.3V or 5V from the DUE to RESET and SLEEP etc If you use a A4988 you can follow this instruction or this link which include some sketch code to control a motor.

Re: Building P3Steel - Steppers will not move - 8 years ago

check the orientation of the steppers

Re: Building P3Steel - Steppers will not move - 8 years ago

if you use a ramps look for the ramps test code.

Re: RAMPS FD with robotarm - 8 years ago

Why do you want to use 3d printer firmware to control your robot? You don't need that firmware or the RAMPS-FD board to control stepper motors. You only need two pins from your DUE to the stepper driver to control STEP and DIR

Re: RAMPS FD with robotarm - 8 years ago

Did you modified this RAMPS-FD? If not please read I did a quick search and from what I read you send ASCII codes to the Sciento CS-113 to control it (http://pepijndevos.nl/2012/04/09/sciento-cs-113.html). So why do you need a RAMPS-FD board and 3d printer software? Do you want to make a 3d printer out of it?

Re: Why no affordable 32bit electronics - 8 years ago

Quotearthurwolf* As soon as those cheap RAMPS, two years ago, started appearing, the number of reports of dead/burnt boards in the community sky-rocketed ( ask anybody who is helping on IRC on a regular basis ). This clearly shows the difference between produced-to-specs RAMPS, and these very cheap RAMPS. But is that because of the cheap board being build so bad they start burn down your house (y

In terms of the fan, yes I do have a fan. But for that, as well, I have not touched the settings as I have no idea which setting works and how it works...

Re: Optical mouse sensor as position feedback - 8 years ago

QuoterklaucoQuoteFrans@FranceCould it be because of the acceleration profile at higher printer speeds that it's missing "steps"? Most probably. Unfortunately, it seems that it's a "feature" of the encoder - to provide somehow better feeling for the mouse user - as you move your hand faster, it tends to gradually increase the steps in random numbers to deliver "better feedback". For a mouse user,
