I have looked in the source code, online documentation, old PDF documentation, Googled, etc. and I cannot find any information on how to set up 'Disallowed areas' in Cura official releases (non-beta versions). I've come to understand that it should be supported in the official releases, but maybe called something else. I'm needing to set areas in Cura that should not be printed on. Any/all help is greatly appreciated pointing me to any kind of example, reference, documentation, etc. Thanks!

I guess this is in the BETA version of the software, because the only information I can find on it is for 15.06.xx Beta. Sorry, but I think I'll wait until the final release to try this.

I'm looking through the (very old) docs and searching the python code, but I can't find any references to Disallowed areas. Any help where to find this setting?

Is there a way to set the X & Y start offset for printing that is different than the (0,0) X/Y Origin? Like setting margins on a paper. Let me explain: I have an JA Aurora A3 Pursa I3 printer (a mighty fine printer IMHO). The way it is set up, the print head origin X&Y is actually off the bed by 30mm each way. I kinda like this in that there's no way to slam the tip into the bed when it returns to origin if your bed it not calibrated. Plus when you are unloading/loading filament, it doesn't just dump all over the print bed to be cleaned up later. But I digress... The way the manufacturer gets around this is by specifying a print area larger than the print bed. But then you have to remember not to place anything too close to the X/Y Origin or it will miss the bed. So I was wondering if there was a way to specify print area separate from print origin in Cura, eg: Print Origin (0,0,0) Print Area (30-210,30-210,0-180) (X,Y,Z) Then the layout display in Cura would just show the printable area on the grid...kinda like margins on a paper. Thanks!

You'll laugh... It's a Chinese kit: HCC Convenient 3D Cost: $150 (1,000¥) Trying to squeeze every Yuan out of it! Probably expecting too much - but learning A LOT! So when I've saved enough to buy a GOOD printer, I'll know what to look for and what to avoid. Thanks for all your help!!

No changes with the banding. The 'Gold' color does show it the worst. Guess I'm going to have a zebra striped Dragon! It's gotta be a Z-Motor issue as its always at 5mm no matter how big or small the print. And the new Marlin software made no difference there. Oh well, it was a very inexpensive (cheap) printer...

I looked at that - many times. I was thinking 'Dang, I must have installed the motor on the wrong side of the printer!' But, no. I checked the instructions, video and photos many times and they clearly show the X-Axis motor mounted on the left with the zero-stop switch on the right (as you look at the front of the printer). However, you are right: If I reverse the setup and put the motor on the right side, and the stop on the left, it would match the Cura screen and everything would be shinny. However, I would have had to swap the left and right panel sides, flipped the bottom board, installed the main board on the left (instead of the right) to match the mounting holes and re-run all the wires. Basically a rebuild. Ugh. I've thought about telling them they should change their instructions, but they didn't have a clue what I was talking about with the printouts being mirrored...

I installed the latest stable version of Marlin on my Adrino style board and am happy to report that the blobs are not nearly as bad! In fact, they are nearly gone! I was reading the release notes and it said it uses 'predictive' pathing so that it doesn't just zip around corners and fling filament, it slows down instead. Makes for a much nicer print...however, now the time predictions in Cura are about 25% under... Guess you can't have everything!

I need to correct the title of this post: It's not mirroring on the Y-Axis, its mirroring on the X-Axis. as the X-Axis is on the opposite side on the printer as it is shown in the Cura software. The mainboard on my printer, MKS MINI, crapped out the other day and I just got a new one in today. Having to load new firmware forced me to download the Marlin source to configure, compile and upload it to the board. That revealed some settings that allowed me to fix this issue with only a slight hardware change: 1. Plug the X-Axis stop into the +X socket (Max Position) from the original -X socket (Min Position) 2. In Configuration.h, set the INVERT_X_DIR true 3. In Configuration.h, set the X_HOME_DIR 1 Now the print head moves positive from left to right and I didn't need to move the X-Axis stop, just redefine it as the Max instead of the Min. Now all my printouts are WYSIWYG without having to mirror it in Cura

It says its compatible with the Pursa Mendel I3. And it does print (after assembly - its a kit) It just mirrors the objects, so I have to mirror it in Cura so it prints out correctly. Otherwise letters/words are reversed, etc. It appears to be because the Origin in Cura is in the left-front, but the origin in my printer is in the right-front.

I just decreased the 'Overhang angle for support (deg)' down from 60 until it supplied a support.

SandervG, Thanks for your reply. It is supposed to be a round sphere and I'll read up your blog on how to improve overhangs - thanks!! Once I get my new main board tested and calibrated (the old one fried), and read up on your blob, I'll run another print with a sphere and see if there is any change and let you know. Thank!

Thank you SandervG and neotko for your replies. The color and surface are difference. Notice on the rounded edge on the right that the darker color bulges out more than the lighter. It does happen on all my PLA colors, just this one 'Gold' (ha) color shows it up the worst. Just two days ago the mainboard on my printer fried - would not move any motor plugged into the X socket. So today I just got in a new board (MKS Mini) and have loaded newer Merlin software on it and testing/calibrating it now. At this time, I'm only seeing a +-1c change when printing. That could be from the new firmware, or not. I'll keep monitoring it. It is interesting that the banding is occuring at regular 5mm intervals. Perhaps a Z motor issue? After I get it re-calibrated, I'll run another big print and see if there is any change. Thanks!

Hi. Thanks for the response. I did contact the company, Shenzhen-Hong Cheng Technology, Ltd, and they said "you must mirror the print on the Y-Axis" before printing". I don't believe that. There must be a way to set it either in the printer on Cura so that it comes out right without having to manually flip it. I can live with the Origin in Cura being different than the Origin on my printer, but I don't want to have to flip every object before I print it (and then forget and have to toss the whole print in the trash) I found the Printer's Main board. Its a MKS MINI. From the looks of Googling it, it seems fairly popular/standard. Maybe there is a firmware setting or jumper setting on it? I looked through it's menus, but there is nothing on the screen to do that. Thank you for any help/ideas you can provide!

Thanks. I looked, but no such setting.

I'm getting these colored bands on my printouts. I've tried many different settings to resolve it, but nothing is working. Anyone have any ideas what might be causing it? (See attached photo) Thanks!

Anybody??

Anyone have any ideas why I'm getting these blobs on my prints? I've tried different PLA print temperatures (190, 200, 210) but that didn't help. Thanks!

I designed yet-another phone holder in Sketchup but Cura is not suppling a neede support (see linked screenshot) Looking at the Layers Mode, it is only creating a support for one side of the Qi Charger Holder, but no the other, detached side next to it. Is there a way to fix this? Missing Support on Right Arc Thanks!

Hi! I have an off-brand Chinese printer, Convenient 3D. The instructions said to select 'other' in Cura. Everything prints great...except the print origin in Cura is left-front, but its right-front in the printer. Also, the Y-Axis appears to be mirrored on the objects printed. Any way to correct this in the Cura software? Thank you!!
