Hi @lmiksch. It looks like you haven’t been receiving any of my email responses, so I’ve gone ahead and re-opened this thread to address your questions and concerns regarding Passthrough prints. I see @rbtdanforth was able to offer some great tips to help with manual alignment.
I’ve included my earlier response below:
… I have included some answers below to the points mentioned in your response. I know it is frustrating to have a long print run only to get interrupted and require restarting the print from the beginning. The biggest factor in recovering a Passthrough print is the point of failure, or interruption.
1. I have just finished a segment and my Glowforge is aligning for hours without a conclusion. How long should one wait before giving up? Restarting from the stored pictures just taken would allow me to turn the machine off and refresh everything
The alignment process can vary depending on the design used, but if you notice the automatic aligning process hanging or taking a very long time, manual alignment and Set Focus may help. Aligning manually lets you drag and drop your design into place. When you choose to align manually, a new design called “Pro Passthrough Remainder” opens. The design will consist of the remaining unprinted portion of the print. After you choose “Align Manually”:
- Turn the Passthrough toggle back on.
- Reset the material and step settings if they have changed.
- If you’d like, you can lift the lid and reposition your material.
- Use Set Focus by clicking the gear, selecting “Set Focus”, and then clicking on the material in the place where you plan to print.
- Line up your design.
- Press “print”
- Continue as usual with your Pro Passthrough print.
2. Oops - lost my internet - or oops lost my power
If the Glowforge connection drops, or if your internet service goes offline, you can recover the print once the Glowforge reconnects with your network This can also be recovered if you accidentally click our of the Glowforge app page. To recover from that you can click back and resume the print. Be aware that the material should remain as is in the print bed to help with this.
In the event of a power loss, that will unfortunately cancel the print and need to be restarted.
3. I am 6 hours in, just completed the second of 3 sections and I have to leave.
You have the ability to pause any print if needed between print slices/sections, however we highly suggest that you never leave your print unattended or out of view.
The align manually steps may help in some situations where a Passthrough print needs to be paused, but canceled prints due to opening the lid, or power loss of the unit will most likely need to have the print restarted. I’ve included a link to our support page with more detailed Passthrough information as well.
