I hope you enjoy.
Expertise talking loud in this episode!
I have seen so many people making "100% precisely" fixtures and failing bad when assembling all parts together.
The main secret for a good alignment is to make the key joints adjustable, period!
Thank you for sharing your experience and helping us to not make known Common mistakes.
Thanks Eddie.
We are seeing the butterfly emerging from its cocoon.Good job as always.Looking forward to seeing it flying some chips.
Thanks Stipples2
With my luck it will be a moth. Lonomia obliqua

Peter I like the fact you are able to make a lot of adjustments for this machine that you crafted and manufactured yourself. I have a similar type of machine that uses the bearings to glide over a piece of metal like v grove bearings and I have found over time they need adjustments. I can tell when the bottom bearing is not rotating like the other bearings on the same plate. I have a GarageWorx CNC and I had to go through and modify the bearing slots so they do not fall out of a adjustments. So far so good. We see over a period of time how long it will stay that way. I had issues with the X Axis chatter and not cut consistent when the router cutter going against the wood.
Thanks D Zee
I must say that I have never had a bottom V bearing bind up. They seem to keep going and going.
Cheers Peter
That rack and pinion set up looks really simple..love it
Thanks Amos. It is about as simple as you can get especially when you buy the drives in kit form like I did.
Cheers Peter
Thanks! As complicated as necessary but not more complicated than necessary - KISS.
Thanks Edgar
Love the spring loaded rack....
Thanks Diego. Can't take any credit for that as they come like that.
Cheers Peter
Don't ya love that drive setup. 10 out of 10
Thanks Paulman50
Looking good Peter cannot wait to see it move and cut
Thanks Andrew
I have been a long time member of your channel and this has to be the best home built upgrade I have ever seen. I really like the rack and pinion drives and I am considering doing the same to my 24”x36” machine, just need to machine the plates and other items needed. Prior to doing my upgrade I need to finish converting my mini mill to cnc. So many projects and not enough time. Great job sir. Cheers!!!
Thanks.
You are too kind.
Cheers Peter
Really enjoying this machine upgrade series Peter. Well done for sure!
Thanks Dave. Taking a bit longer than I thought it would but enjoying it.
Cheers Peter
nice upgrade Peter. I am planning an upgrade on mine too, possibly this year already. My x will also have a R&P, but i am going to go for a rotating nut on my two y-axisses.
Keep those video's coming, cheers
Thanks Staf
All the best with your upgrade.
Cheers Peter
A great job Peter, I am looking forward to your next video, Stay Safe.👍👍👍
Thanks Lou.
Cheers Peter
Looking good Peter. Thanks for the videos on this upgrade. Will you be producing a suppliers list for the various parts? The 8020 ain't cheap here in NZ! Cheers, David
I will probably do something in Part 6 as I have had a few requests for information.
Cheers Peter
Looking good, come a long way from your first vids thank you very much for getting me into this hobby.
Thanks Gavin
Great help thanks a 1.000.000
You can also use a car jack to adjust the gantry to the good height
That would probably have been the better idea. I used it last time when I did the Y axis upgrade.
Cheers Peter
Hi Peter, once you machine the table flat the height will be perfect with respect to the spindle. The height adjustment needs to be done prior to machining. The final machining will remove any remaining error. :) What, if anything do you use to lubricate the rack and pinion?
Thanks Eric. I don't lubricate the rack and pinion and they still show no signs of wear after 10 years of use.
Cheers Peter
Nice build where did you purchase the reduction drives? Cheers
www.avidcnc.com
I will add it to the list of components with links.
Cheers Peter
Thanks for sharing have a blessed day in the name of Jesus
Thank you! You too!
Mr Passuello good day, love the work, and love the channel, three quick questions, can you tell me what profile you are using for the gantry and the model of the linear rails? and do you have any problems with edflection across the length? I am looking to upgrade my machine to an aluminum gantry and it is 6 feet in length...
I plan to cover this in Part 6. The extrusion is 80160, the length is 1200mm and the rails are cheap Chinese 20mm linear rails & bearings. No brand.
Cheers Peter
@@cncnutz Thanks alot, stay safe.
Nice job ... 1st reply too :)
Thanks Adrian.
Please tell me what is the actual Z-Axis complete weight with and without spindle motor.
Your in luck, I actually weighed it. 8.7Kg without and 15Kg with the spindle. Another 3 Kg for the X axis plate if you need to know that.
Cheers Peter
I am so glad you use Kg and metric units.
Can you give me link of the z Axis? I am not found that on aliexpress
Where i can buy the rack and pinion Drive?
I wish I had used rack and pinion. I used ball screws which makes my machine quite slow 🙁
Slow but stronger and more precise... Everything has a price!
Notice that Peter is using a reduction for the same purpose!
You can install a reduction to increase the speed as well.
