Just to close out this thread with an answer, should others reference this...
I'm not sure if updating the firmware, which was part of the Cura software setup wizard, was what fixed this.
After powering the machine off and then making the appropriate changes to the limit switches in the front, its working (in another thread, but the print head was ramming and crashing around at the begining and end of a print)
Strange, as the connections were all fine.
But once I pushed the limit switch for a moment and let go, it would continue with the next sensor, then the back, then the Z. Then we moved on to the bed levling.

Aaron, we're going to have to agree to disagree.
I asked questions, I'm sorry. Apparently my co-worker and I aren't as smart as the rest of you.
-
Great! I hope you aren't just following instructions without thinking about it - I hope you understand now what the limit switches are for? And how they work (at least mechanically)?
Umm, yes I know how they work. Use them in the robots. However for whatever reason, when the very same limit switch was pressed the other night, it wasn't progressing along.
Who knows, maybe the flashing of the Marlin Firmware helped?
-
I had a bit of plastic on the tip so my bed leveling is a bit off (as noted when started a test print)
Like you said, trial and error.
The test print didnt have the CLANG CLANG CLANG effect...so indeed, progress
-
Hey that worked!
-
Hold I've double checked where they connect to the controller, that part is good.
Will try hitting different switch as you suggest
Hold down til i get a different prompt or a few seconds?

Look, I've been following the limited directions for Cura. Your shoe analogy makes no sense.
I've worked with software and written software long enough to know that if the problem gives an error prompt, you do as it says and it stops there, chances are, there's a problem. Where in the Cura documentation do you see anything about randomly hitting the other sensors, hoping that will move it along? There isn't any. That's why I asked the question, posted to the support email and asked, with screen shot, on the forum. I don't want to argue with you. I just want to understand what the error is, what I should do about it and further troubleshoot it.
Now on to the limit switches...
I did find that when the Ultimaker goes to that far left position, the Limit Switch wasn't making contact at all. Same with the one front right (which showed the error in Cura).
I did get an email from Support...
Hi Paul,
There could be a bug in the software, so you can just continue.
Do you have the UltiController? Because then there's another way to test the end-stops.
Kind regards,
Marrit Hoffmans
Now I need how to figure out how to Test that in the Ulticontroller

Print done, uploading to YouTube now....
-
Certainly, I'll fire up the Sony Bloggie and do a test print (since I am also curious if my first layer is low enough too)
-
I did the zip-tie thing on my extruder as well It seems to really help
-
I agree, its been a fun week watching a pile of motors and wood print out some nice looking stuff last night
Clearly there is still some tweaking to do, such as the ramming into the front left corner at the start of each print.

Aaron,
Place yourself into the shoes of a new user/customer/builder
The threads are loaded with people having problems with pulleys, belts, clogged print heads and the like.
We came to the forums to ask questions along the way because we were trying to AVOID those issues others were having...and many are still having. I find it completely ironic that you chastise us for asking for assistance at areas for concern in a forum titled "Questions & Answers (Help Each Other)"
After spending $2400 USD on a wood-based kit (Ulticontroller, Second Extruder, base kit), yes, I will continue to ask questions as I try to avoid roadblocks and other expensive issues.
Many times during the build I wished I had gone pre-assembled. Two of my peers bought Solidoodle 3s for a lot less money pre-assembled and were printing moments after unpacking. I'm still convinced this Ultimaker is a superior product And to me and my co worker, the community support was the selling point.
But now you say to new customers like me.....stop asking..."No offense"?
We used the Wiki and there were some areas that were great (inventory list of what is required), relevant pictures and so on. But there are many areas that we had to rely on the comments in the bottom since the Wiki did not entirely reflect the latest version of the kit. In hindsight, after having built this, I see some areas of confusion are language based, which I would like to offer to help clean up and clarify.
I come from the IT world, have built an aircraft kit, two aluminum R2-D2s and the vast array of electronics, servos, motor controllers, LED lights, PCB construction and so on. I'm used to well laid out details for assembly and other processes. And I'm used to metal. Wood...I'm afraid to break and wait weeks for a replacement from the Netherlands.
Anyways...I'm not offended by your post. But I will tell you that I think the daunting assembly process is what keeps many potential customers away. The assembling version for $700 more...I wanted to but based on the competition, simply too much. So...we took a chance on building :cool:

As for Cura, there's no instructions I could find that say to hit other limit switches if that one doesn't come up
That's been my frustration to, I was waiting for the detection routine to give up/move along to the next test...and it never did. CURA is ok but the documentation for the first time setup/calibration is a little light. Especially if it doesnt go right, as I found out
I can try push the other switches...I wasn't ignoring you. I simply had no idea how to proceed, thus the post (I did submit a support ticket to Ultimaker Support but no reply yet)
-
Firefox bombed on me earlier, it looks like one of my replies didn't make it...
I did level out the platform and to fine tune it some, as Illuminarti suggested, further refined it by adjusting the acrylic bed with the 4 screws. Since I did that, I printed the gear and owl, which look really good now. Before, yes, it was plowing into the tape some.
Here's how the first layer of the gear printed. Its not flattened out as your vimeo link showed...but it wasn't plowed into the tape the first pass or two...so...getting closer?
-
Scaled down to 45mm tall
-
Should i use the adjustments in the bed (those four scews) to lower that a smidge?
Well I havent had a way to go beyond the error I got in Cura. It asked to touch the front X limit switch, I do....and the program stops there.
-
Well recall it failed the calibration (see post from yesterday)
-
What would be some good test prints, like the owl? Do you have a direct link for the med size one like you printed?
-
Does that cause damage tho?
Ok first print, let the suggestions fly!
-
Printing now
When it first starts, it bangs/bumps (not violently) into the left side, then starts its work....what's that?
-
Yes comes with black set screws, silver ones in
-
Wow, guess what i found? The X axis set screw flew out.
Back in!
Looking for a tinhy allen wrench to torque that bastard in
So no changes other than .2 mm

Quick question...bed to nozzle...

I'm still tweaking to get that first layer to look "smooshed" as you guys have kindly advised.
On each edge, as I calibrate and adjust the four screws on the bed, I'm using a piece of paper to guide me. If I can't pull it back and forth, I loosen it slightly.
But I'm not quite at that "smooshed" quality of first layer.
I know this calibration can take time to nail down, I am curious what worked well for you?
Again...I know I ask a lot of questions...but I appreciate your feedback. :geek:
