Topic: Extruder doesn't stop when it hits the end of the x or y axis

To view a video of this, look up the user "allegrovivo" on YouTube. The most recent upload is the video that shows the problem. Soliforum won't allow me to post any links.

As the subject states: When the extruder moves along the x-axis towards the right side, the endstop stops it from moving any further. If I keep hitting the button that moves it to the right, it won't budge. This is how it should be (and how it used to be). However, when it moves to the left, it will keep trying to move if I endlessly push the button, creating an alarming buzzing sound.

The same happens when I move the y-axis towards the front of the printer. It will keep trying to move forward no matter how far I ask it to go.

It seems to me that there is something messed up with the programming.

I'm still researching solutions, but I thought you lovely folks at Soliforum would be able to help me out.

Thanks in advance!

Re: Extruder doesn't stop when it hits the end of the x or y axis

I haven't checked out the video yet since when you type in allegrovivo, nothing related to 3D printing pops up.
Some more information would really help.
Which printer do you have?
Did you buy it new?
How long has it been doing this for?
Have you recently changed any settings?
And how much use has it had until this issue came about?

Also...if you cannot give a direct link, at least change the video title to something unique we can easily find.

Check the size settings in configuration/printer shape and make sure they match your printer.

Re: Extruder doesn't stop when it hits the end of the x or y axis

Hi there, the name of the video is "soliforum 12b68" on YouTube.

I have a Solidoodle 4. I only did one test print which turned out fine (the one suggested in this article provided by Solidoodle called "How To Print")

I didn't mess with any of the settings. I've only had the printer for a week.

Here is the story: After setting up the printer with the instructions on Solidoodle's website, I did a test print, which came out fine. After that, I printed a couple of small things, which also turned out fine. A few days later, I went back to the printer and attempted to print a simple squirrel found on Thingiverse (under the collection "Get Started"). After a few layers, the left side of it would unattach from the bed and curl up. After closer investigation, I noticed that the bed was curved (the middle was higher than the left and the right). I tried to calibrate it so that it would level out (by turning the screws under the bed), but I couldn't manage the leve it out. After some research, I found out that it might be defective and that I should contact Solidoodle.

A couple of days later, I went to take a video of the print bed to prove that its curved so I could send it into Solidoodle. That's when I was moving the extruder up and down when I realized that it bumps against the left side of the printer and continuously does so if its prompted to (but it refuses to move when its all the way to the right).

Again, it's hard to explain. Please search for the video "soliforum 12b68" on YouTube.

Thanks so much for taking the time to help me.

I agree with ronsii on the settings. But next time you notice it giving you that grinding noise, command the x and y to return home. This will send that to tap the flipper switches. Then continue what you you doing commanding it to the opposite end. If it is still making the problem, you have the wrong settings under printer shape.

My bed warped after a month of use. Instead of waiting for SD to take their sweet time to send me a new one that I would have to fix, I just tossed on a mirror. My platform is now perfectly flat and I get superior adhesion .

Re: Extruder doesn't stop when it hits the end of the x or y axis

We have returned the extruder home several times but it continues to do it. I guess when I'm printing, I won't be sending the extruder to the ends of the bed, so it's not really that big of an issue.

When you and Ronsii say change the settings, do you mean under "Printer settings" > "Dimension" in Repetier? I have the x-max and y-max as 200 and the x-min and y-min as 0.

Azerate, as I do more research, it seems a mirror may be the best choice. Where did you get yours? Was the process of replacing the bed difficult? Which tutorials did you use, if any?

What exactly do you guys mean "printer shape"? Where can I find these settings? Thanks for your patience with me. I'm still new to the 3d printing world!

I never got a new bed. I just went to a local glass store and had them cut 2 6''x6'' mirrors (I run SD2), and slapped it on. You can either use those small document clips, or mist some hairspray (prevent said hairspray from getting onto your electronics, belts, etc) on the kapton, then put the glass on. Many users swear by this technique. Then you have to adjust your Z tab. On the SD4 I believe there is a wheel in back that you turn. This will lower the height of the tab. Since you are essentially raising the bed by 1/8", you must lower the tab to prevent any damage to your hotend.

Please bare in mind, though, that you can only do this if your bed has a dip. If your bed is raising, you will need to look at replacement which SD will honor.

Yeah that may not work for me. It is raising in the middle, not dipping. I'll contact Solidoodle about this. Thanks for the advice though. Should the bed ever dip in the future, I'll more than gladly get a piece of glass!

Re: Extruder doesn't stop when it hits the end of the x or y axis

You should contact SD about a replacement.  That being said there is a simple solution to your problem.  Buy some Kapton tape and add a strip or two on each side to act as a shim.  Then spray a piece of glass with aqua-net and stick it to the bed.  The reason using clips to hold the glass is not recommended is that it will warp the glass to match the warped bed.  It will take a couple of heat/cool cycles for it to stick good and use plenty of hairspray on the underside of the glass.  A light mist on the top of the glass will help with adhesion.  I have used this technique on more than one SD3 so I know it works.  Even with a flat bed I would still print on glass as there are so many benefits over Kapton.

Re: Extruder doesn't stop when it hits the end of the x or y axis

My build plate was warped right out of the box.  I also can't get an 8 x 8 build area as the fan on the extruder will run into the X axis motor bracket.  All my settings have been verified with pictures and screen shots.  I haven't been able to print anything round either, even after doing the Y axis belt adjustment process.  Still waiting on my build plate.  So far, I haven't been very happy with the purchase.

Bvaught, when did you ask for a replacement?

Re: Extruder doesn't stop when it hits the end of the x or y axis

It took a couple of days of me sending pictures, but on Thursday of last week they gave me an Rma number to replace it.

My personal recommendation:
*Replace the aluminum platform
*Buy a piece of glass to size said platform
*If possible, buy a reel of kapton to cover the platform before placing glass. If you have kapton, you can easily spray some extra/extreme hold hairspray onto the kapton wardjr and myself mentioned, as well as the top surface.
**If you do not use kapton on the kapton-on-aluminum+glass process, you will need said document clips and hairspray.

But if you have a bulge rather then a dip, you NEED to have to replaced. Nothing good will come from a factory defect to that level.

Re: Extruder doesn't stop when it hits the end of the x or y axis

I had the same problem with a supposedly warped bed. I put a 1/4 inch glass on top of it (glass is the flattest thing you can find aroud!) and surprinsingly I still had this warped bed...

I found out finally that it was my X rods that were bent. Same issue as described here : extruder at 0.2 mm in the center of the bed, and around 1 mm on the sides...

I changed all the carriage with the lawsy carriage, and brand new rods, and don't have any issues no more. But my machine was no more under warranty, and I bought it used.

You should check if your bed is really warped, it is probably not. My suggestion is you should ask solidoodle to replace the carriage of your machine.

Mine was very obvious.  I put a level on it and I could rock it back and forth.
