Is it gcode or hardware ?? February 26, 2015 10:02PM |
Registered: 9 years ago Posts: 42 |
Lately it seems like I have more print failures due to the printer making some kind of strange move,
like burying the head into the material, raising the head and continues to print,
sometimes it just goes out in one direction for no reason then returns to the print and continues to print.
This is starting to bug me, I have no idea why this is happening, is it bad gcode, or something wrong with my hardware.
Thanks,
John

Do you use slic3r? Check the gcode on the host screen. Turn on travel moves to see non-print moves. Check each layer. If it checks out ok then the problem should be something else, not gcode.
Sometimes it can be gcode. I always I check the layers in the simulation before printing and a couple of times I discovered it sliced cavities where there should be just infill.
I found out later after much frustration that slic3r Print settings can somehow become corrupted, messing up the slices. Then I thought of slicing with the default settings and indeed, the problem went away. So I made new settings from that and so far so good.

I mean after slicing in repetier host, you will be brought to the gcode panel. You can check the layers generated by the gcode on screen.

boksbox - thanks, I understand, yes I have been checking it with Repetier.
vreihen - Yes, I am using belts and pulleys and they do seem a bit tight, I'm new to this but how would tight belts affect the print, I have not tuned my steppers, not sure how to do that ?
Thanks

Here's a new one, I was printing this morning, all was well then it printed almost an entire layer at like zero speed, it was moving but barely, then it started printing normally again ???
Do you by any chance have a full graphics LCD Display fitted and I am assuming here that you are using a Ramps setup?

Yes, I am using the full graphics with a Rambo board.

There's your answer it is a fairly well known fact that adding a full graphics controller onto 8 bit control boards when coupled with a delta causes drop out.
The Mega 2560 based boards can't cope with the extra processing that is required.
Doug
WOW, that's exactly what seems to be happening.
I'm disconnecting right now and change the firmware file to disable it.
I never knew that, I do have a Smoothie board in a box, would it be worth the change to it ?
Thanks !!!

Before you do that, try this - reduce the DELTA_SEGMENTS_PER_SECOND to 80 in your firmware. See if there's any improvement in stuttering or hiccups.
boksbox, I did that and it was like night and day, not one stutter since, and I have not had one print failure since I took off the display.
Thanks !!

Hi all
Just building a mini kossel now.
Does this happen with all LCD attachments to ramps or is it just the full graphics version ??
Thanks
I'm not sure on that one either, anyone else know ?
I believe that the simple Graphics card is ok (Just) I know of several kits that are supplied with it and they all seem to work.
But if you want a really nice Graphics display (Touch screen as well) then you need look no further than the DUET controller with PanelDue display combination by DC42 see and

I'm using RepRap Full-Discount LCD Display Controller / Arduino Mega 2560 / Ramps on my Kossel Mini. It works fine. I also had the stuttering problem and "pimples" on curved perimeters at first.
I searched the forums and besides upgrading the electronics, there has to be another way. I found in one (I forgot where, I'm sorry) to reduce the DELTA_SEGMENTS_PER_SECOND. One said he even went as low as 50 to get rid of the "pimples".
The default value of 200 is simply too high for the Arduino. Setting it low will allow time for the processor for other tasks such as display control.
Glad it worked for you too.

Yes ive been looking at that but id like to get the bog standard kossel mini working first. Ive learnt my lesson the hard way about already upgrading while buildingQuote

The one thing i really like with Ramps is the ability to change the stepper drivers . I've just put 3 Trinamic 2100s silent stepper drivers in my prusa air 2 and its like a new printer. Doesn't make any noise at all except for the fans.
I do like the idea of an LCD touch screen though. I only installed a full graphics display controller on my Air2 a couple of month ago and surprised myself how often i use it.
