I guess that gap infill goes on the bridging acceleration setting?

[oblomov6]

Sure thing! As soon as I get past the last calibrations!
Still having some minor(but of course Hugh in the long run..)

First my ATX dies when setting heat bed temp. (A issue I have ignored so far because i’m printing in PLA) it is a 500w 22A ATX with a 20W lightbulb on the 5v rail. I am a little baffled, does anybody know of a possible solution?

Second, Gap infill’s misses the perimeters, I guess it may be some sort of backlash. But I am beginning to suspect that this can have a link with the ATX problem(causing extra vibrations etc.). As the steppers does some “pausing” on the MQ15 sklic3r setting you provided(Lowering the trimpots does not help and taking them higher only results in a terrifying buzz from the steppers). So together with some not so smooth movement now and again So I wonder if the ATX provides some inconsistent power or some other interference.

Otherwise it prints straight and nice vertical perimeters, I will post some pictures as soon as I get some perfect prints :)!

Tinkering continues tomorrow, godnight!

Great!! Tahnks a million! It workt good, but just an houre into the calibration printing a arm came loose and made the real problem apparent… It seems I have been a little bit sloppy with the mounting of the arms. Good new tough, it is now mounted secure and printing better than ever! I will probably try some fine tuning with the phantom in the weekend!
Sweet!

Best regards and thanks,

Hello Quentin!
Is the Calibrations soon to be up?
Tried to figure it out yesterday, got really close on a trail&error but I would be really glad to get some calculations instead!

[oblomov6]

Well, everything seems exactly spot on… Unfortunately.. I remember that you talked about a phantom in the “How making calibration foolproof drove me insane…” topic. Did you eventually do this? in that case I would love to get both the model and the calculations.

The hall effect sensors would go onto the z-axis smooth roads and the magnets on the drive wheels. When in home position these should line up, I.e. magnets trigger the hall effect sensors.

This position is arbitrary as the calibration process will account for making a individual offset.

Hope this was more helpful!

Cheers

[oblomov6]

Ok, I will check this first thing tomorrow! Hopefully it will be something there that I can fix! That would save me some trouble calibrating!
Other than that I must say that the machine is a beauty to look at while printing!

Also one question regarding the J-head, I was thinking about adding two 40mm fans to the toolhead for print cooling and j-head cooling. How much weight do you think the arms will handle? I was thinking of doing a variant of this cooler: http://www.thingiverse.com/thing:119061

Hello!

Under the Topic “Reprap Morgan Building From Asia!But I need a help!” Quentin has shared some nice Pictures that will explain which position is the home position I.e. where the endstops should be triggered.

Hope it helps

Hello!

My Morgan is now up and running! Thanks for all the help(and the actual machine)!

It prints fairly well though I will have too fine tune it after hand, and I noticed that my prints gets a little bit “diamond” shaped. And I have rerun the calibration a couple of times, but still comes out almost exactly the same.
But I guess I could solve this problem with the x-y scaling?

Anyway it feels good to at last get my endstops(took a month for them to be delivered)

All the best,
Gustav

[oblomov6]

Yeah a I could try a video when I find some precious time, a lot of work now(a good thing though…).
Tomorrow I will have a small course in my previous school(architecture), so I’m trying my best to get as much as possible running on the Morgan :D. Would be nice to have two fully functioning Repraps with me, but that is a little to late now.
After that maybe we will have more Swedish morgan builders..

Anyway, I do have jumpers installed under the stepper, though I realize I have all 3, which means 1/16 right? How would I configure for my 1/32?

Ok, now I need to rush to work, thanks for all the input.

Regards,
Gustav

Thanks for the help Quentin! Now the homing works well!
But i still have a little problem with the arms going wild…
It seems that the home position is lost directly after homing because if I hit m360 the arm goes way to long into the back and if I try to just joggle the pronterface controls with either x or y with 0.1mm the arm skipps over half the platform. m114 then shows x 0.0 y 0.0 z0.0 etc.

Here comes the values right after homing(is this looking right?):

ahh, that information will spare me a lot off, more, pain… I got a ton of magnets so It would be no problem to set one on the side. Though It will be more tricky for the z axis, but will probably work out fine.
Is there any other advantage to the a1101 or will It work out well for me with this configuration?

Anyway thanks for the help, it’s getting late here and need to go to work tomorrow so will try this out tomorrow.

Goodnight!

I think they are wired correctly, they get triggered right(being open when booting up the ramps). But something I find odd is that they stay triggered after passing. Shouldn’t they open again when the magnet has passed?

Thanks,
Gustav

[oblomov6]

Hello again Quentin! Now it is near a test print… well my batch of hall effect sensors have not arrived yet, but Everything else is in place and x-y have endstops.
So I tried out the x-y calibration routine but I can really figure out how it works. I wonder how the endstops work because the homing seem to disregard them, only moving x-y a small step each(always in counter-clockwise direction).
And when issuing m360 the arms sometimes go really wild :D, and sometimes only move a small bit. if I then get the position and put in the offset the new homing will put my arms all the way back and touch my ramps(I put it ontop) efficiently ending my callibration…

Anyways I would be thankful if you could give me some insight into how it works with the endstops etc.

Thanks for all the good work and help, really appreciate it!

Regards, Gustav
