So with covid supply chain issues there isnt a sheet of half inch MDF within 100 miles of me for a spoil board for the 1515 i just ordered.

Can a guy use 3/4 inch instead?

 

hi there
any one know what some times the cnc goes -10mm in Z axis at rapid movement only before cutting the G codes?
i`m using Fusion 360 for G-codes

 

If you mean it goes to - 10 and you are using the Openbuilds post processor for Fusion that is correct - it's a safety move to raise Z to avoid hitting any clamps when it moves to the point where it will start cutting.

hi Alex thanks for your response but its going in the work piece not above i know the retract level but only in the first move it goes -10mm inside the work piece in rapid move

 

Just Finished my Lead 1515 but the X Axis doesn't work. I believe the lead screw arrived warped. I have searched the forums and attempted the dry silicon spray to loosen it up but that didn't resolve the issue. The force required to turn the lead screw is beyond the capability of the motor so it simply doesn't turn. I'm at a loss on resolving the issue. Who should I contact for support?

 

Hi,

I have an Openbuilds Lead 1515 with Duet 3 6hc mainboard. I built my machine but I struggle with configurations. I'm using RepRapFirmware Tool to create system files but I keep gettings errors.

Is there any guide/doc you can suggest me to make the first configurations for a Lead 1515 with Duet 3?

Best,

 

Not for an Openbuilds machine, but the link below might help you get started.

Andy Ofori is the expert on the Duet 3 6HC in my Facebook group

Workbee CNC Users Group.

If you don't get on with the Duet there's the Blackbox X32 from Openbuilds.

Alex.

 

Thanks Alex. I applied to join that FB group. There is one thing I'd like to confirm. Can we say that Blackbox is as easy as plug&play and requires minimum or no G-coding? Can I start to work with it immediately with correct cable connections? I'm asking because this is what I saw while watching Openbuilds youtube videos.

 

I have had Duet for the past 4&1/2 years so I'm a little bit biased but yes, Openbuilds have made the Blackbox system as easy to set up as they probably can. I certainly get more queries about setting up the Duet 3 6HC than I do about either version of the blackbox.

Hi again,

My Lead CNC 1515 works well but this part seems like a bit loose to me. I attached a video file. Can you please tell me if it's normal or loose?

Thanks a lot.

 

Way too loose - start by checking the adjustment of your eccentrics - you should just be able to turn a wheel with your finger. Also check that fixing screws are secure, bearings properly seated and lock collars secure.

Alex.

 

The symptoms suggest a fault in the wiring to your Z stepper.

Alex.

 

Thanks for your reply @Alex Chambers. I deleted my post because there was no reply yet at that time but seems like you were writing a reply, thanks again. I thought that it's fixed when I disassemble and reassemble. It worked normally but then same problem occured again.

The answer to your question in the photo - I purchased my LeadCNC in Europe and the company sent me different colored wires and it was a bit hard for me to match with step motors wire colors. So, it looks a bit messy because of the paper color labels I put but it worked smooth till today.

I checked the wiring and connected each wires again but still same issue.

I upload the video again, sorry for confusion.

 

Have you checked the connections at the other end of the stepper motor cable?

Alex.

 

Yes, now I was busy with that. As you already mentioned, this is a fault in the wiring. Checked all connections again and now working fine. Thanks again Alex for all your helps.

 

Hello, here again with another newbie question.

During carving I do not get any problem but while cutting out, I usually get the break/tearout problems as you see in the attached photos. I check the screws/bolts every time but the mechanism is not that loose.

Is there any obvious reason for this?

Thanks a lot

 

Yes, my work fastened securely with screws and bits are quite new. I think my cutting settings are wrong (too fast and deep cut), I go with slower and less deep cut and I didn't get any tear out this time. Thank you Gary and David!

 

I'm here again with another question. Z axis problem.

If you can see the attachment, when I work on the projects which have two or more pieces needs to be cut, I get the cut nicely for the first piece but when my machine starts to work on the 2nd piece the Z axis starts from 3-4mm above. It doesn't touch to the material at all.

I don't have the Z probe, so I do it manual way with paper. But, as I mentioned, for the first part everything goes perfect.

Do you know how I can fix this issue?

Thanks a lot

 

I'm seriously considering getting a 1515 now that I space for one. Can anyone tell me how hard it would be to adapt the "High Z" mod for the 1010 to the 1515?

It looks simple, but I've been bitten by "simple looking" stuff before.
