Need help printing 10 3" pins on wood by this Sat. Print head does not move, stuck at "homing" or "centering"

Thank you for the offer. I will follow up if/when we get to that decision. Just a side note, our robotics team used to build their competition robots out of wood until a couple of years. But, the team wants to keep its history and look and feel by continuing to design the pits, pins in laser cuts on wood.

Ah, edited the shared link. Thanks.

Updated the shared link. Thank you for trying :slight_smile:

Update: A friend who has a GF has offered for me to get these printed tomorrow. GF Support looked through the logs and determined that the Glowforge has an issue with its power system. If anyone has come across this before and has suggestions, I’m happy to take apart (and put back!) subunits to get to the bottom of this. Besides, the high school robotics team members get lessons in repair and maintenance! And thank you all for help!

@raymondking32 has done the most in-depth repairs of anyone I’m aware of.

@deirdrebeth haha, I have done a bit of taking apart, that’s true! The two parts that I have the most familiarity with are the board that the lid’s black ribbon cable connects to at the back of the machine, and the one that the white ribbon cable connects to on the left hand side. I had a similar issue where mine would be stuck “centering”, which was resolved by fixing the board that the black ribbon cable connects to. I did a write-up on that here: Black Ribbon Circuit Board - Replacement Guide

I’d suggest that you try to visually check to see if this board has any sort of obvious damage, such as black burn marks or corrosion. The way the machine knows where to send the laser head, is during the startup, the head is sent to the rough center of the machine, the camera then takes a picture to find the head, and adjusts it until it is centered. From there it “homes” it. If it cannot understand where the head is, then it gets tripped up. This information is all gathered originally through the black ribbon cable (which could also be the problem), sent through that connection board, and then through a separate white cable into the main board on the right side of the machine. Anyway, the visual inspection is where I would start. The part and shipping is much more cost effective than ordering a replacement machine, but you’d have to be able to diagnose the problem correctly.

I found corrosion on my board only after ordering a black ribbon cable replacement and the problem still being present. Had I done a bit more poking around, my problem would have been more obvious.

I’ve reviewed the logs and unfortunately I agree with the determination there is a power supply problem.

Let us know if you’d like to proceed with the replacement offer. We’re here if you need us.

I’m going to move this topic over to Beyond the Manual so the discussion can continue there.

I’ll chip in as well if that’s the route you take.

Thank you. I will look through that. Although, GF Support seems to be sure that its a power problem.

Thank you for the offer. I will ping you if we go that route.

Update: I did manage to print using a friend’s GF and we did give the high school seniors their pins! The GF, though, we decided to accept GF’s offer to send us a refurbished GF. The cost is going to be $851 + $200 (shipping) + 10.1% tax = about $1157.15 if GF estimates hold. I will reach out to the members who expressed an interest in helping the team with the funds. If anyone feels generous enough to contribute to a high school robotics team, please DM me. Your donation will be to a public high school or to FIRST Washington, a 501(c)3 org that runs our competitions. The team can access funds from both pots and your donation is tax deductible. And thanks to everyone who helped - great to have an active community!

What is that? Are you able to take Paypal?

James, Thanks for getting back.

The easiest donation (at his point because school is closed) is through FIRST Washington. The site is Donate Now | FIRST Washington (givelively.org). The key thing is to mention that it is for FRC 1899 or send me the receipt so I can make sure it gets to the team’s booster account (every team has an account with FIRST WA).

If paypal is your only option, you would have to send the payment to me (chandans@exmsft.com). But, that would NOT be a tax deductible donation. I paid GF and I get reimbursed through FIRST WA.

Thanks much.

Okay, I’m traveling this week (road trip from NC to CO) so it will have to wait until I get back to CT. But I’ll take care of it then.

James,

you have 2 options:

  1. Donate to the High School’s Robotics club account

Go to Interlake High School ASB (intouchreceipting.com)

Choose I want to donate to “Donation - ASB Robotics Club”, type the amount. Please send me the receipt.

  1. Donate Now | FIRST Washington (givelively.org) If there is a memo field, please write “FRC 1899” and send me the receipt.

Just FYI, another member of the Glowforge Owner’s forum has donated $50 so we $50 less. Please let me know how much you are planning on donating, so the team can plan accordingly.

Thanks

Thanks. I’ll be in touch via PM. I just got back from CO. You’re next on my list :slight_smile:

Thanks. Or reach me @ chandanas@hotmail.com
