ah, I think I misunderstood your previous post. I agree this would happen if he used wrong printer model or wrong setting (the right half of the picture seems to suggest the printer model is correct). If he place all object at the same position and others prints are good, the possibility I mentioned above is not what happening.

my past experience with xyzware is by default the object is dropped in the center not in the bottom right as shown in his picture. And it is not easy to move the object. you need to click and select the object, the click icon in left and change the x axis number and y axis number manually and separately. That's why I think it is strange he have a object at bottom right.

However, I have not use xyzware for 3 month now, it may came up with option to change the default object drop position or even print bed dimension. It is also a well known buggy program, what you said is very likely to happen. But I don't think it is easy or cheap to switch slicer for Da vinci 1.0A to find out if it is the slicer problem. Move the object to center and try to print again is easy and fast. if the print works after move to the center, then it worth the effort to test the wire harness reliability to avoid more complicated issue in the future.

I'm not trying to question your judgement, just trying to offer alternative possibility in case there is easy solution.

A wire harness issue is not an easy solution on a 1.0a. If this was a harness issue then the issue would be in the endstop. All three wires in the endstop are the same color and very hard even for a tech of 20 years like myself to figure out which is signal, which is power, and which is ground, and then trace them to the board and check for intermittent opens. The only marking on the 1.0 board is x, y, z endstop. The pins themselves are not marked in any way. Not only that but they are swapped at the board compared to the sensor.

Doesn't cost anything, takes 5 minutes, then you can use whatever slicer you want.

Yes, the flash itself if cheap and easy, but the calibration after that may or may not be easy depend on the skill set he have. I wound strong recommend to flash repetier-firmware if he is confident with it and he knows his hardware have no issue for sure.

If he indeed have wire harness issue and he flashed repetier-firmware, then the troubleshoot become even more complicated. It can be calibration issue, firmware configure.h issue or Cura configuration issue.

Repetier for the XYZ printers already comes preset for the 1.0 and 1.0a. and AOI. All you have to do is set the correct machine in configuration.h section before you flash. All he has to do is adjust the offset of the Z axis slightly then calibrate the bed per the manual steps in the XYZ section here. It really is the easiest conversion of all the XYZ printers. Troubleshooting becomes easier actually because you can use Repetier host as well and send m commands directly through console to read endstop status and to move each axis if needed.

I don't think you can change X and Y dimensions or the start position in xyzware. All the settings are set for selected model, unless he use wrong printer model, there is little he can change.

What I meant is he put his problematic object in the corner that is easy to trigger the wire harness issue because filament and y-axis cable have max tension there. If he move the object to the center of print bed it will less likely to trigger the problem.

I know it is a wild guess, but this model is positioned at extreme front right, which is unusual. And that's where the possible problem get triggered easily. if he print other model around the center, the problem may not be reproduced.

That is the starting position his machine is set for. The STL file does not dictate where is starts as there is no positioning data in the STL.

That is done by the slicer when it generates the gcode. I tried printing his STL and it started in the center of my machine where my slicer says to start. In his case he has his start position set wrong and all of his prints will start there. Which this also points to an issue with his slicer.

My guess for starters is his X and Y dimensions are swapped in his slicer settings.

OK, Just share one of my wild guess. I think it is your wire harness issue with your Y axis motor. Check if your Y axis motor wire are connected securely and replace the wire if necessary. Da Vinci 1.0 wire harness is know to cause problem because it use wire that is not resistant to repeated bend.

If I guess it correct, your image is taking form the front, your hotend is dragged towards Y axis min by your filament. My speculation is your Y-axis motor is weak due to poor connection, every time it go to X min and Y max corner, or right toward door side corner, your filament spool drag back after pull to max tension. Normally if you Y-axis motor have enough torch, it will not go with it, but if y-axis motor cable also at max tension at this spot and if that is dragged loose or the cable connection is no good, it will become weak, your hotend will be dragged by filament.

The issue can seems to be fixed on its own but will come back at random time point, replace the wire harness will be more permanent solution. It can become more worse and you will get error 31 or something like that.

I know it is a wild guess based on limited information, but it doesn't hurt to test with multi-meters if you are confident with your skills.

Sorry about bad English, use your best guess if you are not sure what I meant to say.

He did say that this was the only model that did this. So that would exclude the machine as having any issues. Typically had it been on all models then having a 1.0 in the past I could tell you this would be caused by a bad endstop harness. As the machines sees each time that the endstop is triggered as a new homes position and starts from there. But since it only does this on this one file then the way the slicer is using the file is the issues and we all know that XYZ does not have good slicer on the 1.0 and 1.0A host.

I appreciate the help guys. I’ll looking into reinstalling the program maybe that might help as a temporary fix.  I’m currently looking in getting the anycubic right now and using cura.

if you are confident, you can flash repetitor-firmware with your Da vinci 1.0A, and you will be able to use Cura directly.

I don't have anycubic mega i3 printer, but based on multiple people's comments, it is also a problematic machine, their custom service is good, but the cause of the problematic is unknown, so there is not much known mod to recommend to fix it. Read more people's experience on internet before make decision.

If you like anycubic mega i3 design, check out monoprice maker select v2 or monoprice maker select plus, they have heated bed issue and is noisy, but after z-brace mod and heat bed mod, it can be very reliable printer with high print quality.
