Gday Andrew, the results you got on the name plates are fantastic, the cost of building this machine wasn’t cheap but saying that you have learnt so much and enjoyed build it, this is priceless in my opinion, you’ve done a brilliant job and I’ve really enjoyed watching the series, great job mate, Cheers

Hey - thanks Raymond!

@daveswain8295 2 года назад

Good job there Andrew. Bear in mind I know nothing about cnc.. The tool path looks like it is for a plasma cutter, they move the cutter around in what looks like random tool paths but it is done to spread out the heat in the workpiece to prevent distortion. I might be completey wrong of course 🙂 Cheers, Dave.

@learningturningmetal 2 года назад

Thanks Dave and that is an interesting thought. Maybe you are correct. I've since moved on to try to master Fusion 360 manufacturing. Although far more complicated to use, it generates very efficient tool paths. Cheers Andrew

@timjoinson7232 2 года назад

Congratulations Andrew. Quite a machine. This has been a very technical project and I am so impressed that you have overcome all rhe hardware and software problems it presented. The scope to cut accurate engraving is huge. I also enjoyed the Wuthering Heights interlude 😂

Fascinating - I really enjoyed this. The results look really good. Thanks for the candour on the costs, too. Each individual part seems reasonable, but they don't half start adding up!

Saturday morning coffee with Andrew Whale. You asked if it was cool, well it is really very cool!! Great job. A lot fellows in my group are starting using Fusion 360, guess I am going to have to look into it if I ever get caught up on current projects. The bouncing around seems to be something current tool path generating software does. I have seen U-Tube adds where the cutter moves all around the piece of stock where I would have manually programmed continuous cuts. One of the comments mentioned it might have something to do with heat buildup of the tool. I think 3-D printers do somewhat the same thing don't they? Actually going to an outdoor engine show tomorrow ( 5-1-2022) first one in 2-1/2 years! Dick B. USA

@learningturningmetal 2 года назад

Hi Dick. Thanks for the suggestion. I think the problem is the way Openbuilds CAM generates toolpaths. I found that Fusion 360 gcode generation is far more efficient. If you are going to have a look at Fusion, Paul McWhorter has an excellent RU-vid series. If you master 2D, the 3D is relatively easy. CAM is a whole new ball game though. I hope you enjoy your day out. All the best. Andrew

@adaml52 2 года назад

Good result Andrew, Well done. Adam

@learningturningmetal 2 года назад

Thanks Adam! - as you know the electrical side is definitely not my strongest area. I hope you and your family are keeping well. All the best. Andrew

@adaml52 2 года назад

@@learningturningmetal You've done well. Every body good at this end. Take care Adam

@davejenner7966 2 года назад

Great job Andrew, very interested in the Open Builds software, as I have a 3018 that I'm playing with when time allows. Looking forward to the next build!

@learningturningmetal 2 года назад

Thanks Dave. Yeah - the openbuilds blackbox seems really good. I think the openbuilds CNC software is a little basic and generates very inefficient toolpaths - compared to Fusion 360. A same I didn't show the Fusion 360 code running - far more efficient. Have fun with the 3018. Cheers Andrew

@jonsworkshop 2 года назад

Well done Andrew, great result, you must be really pleased. I know you have only just got going with CNC so this is no criticism at all, but if you play around with your cut depths (I.e. Deeper) , it will reduce a lot of the wasted traverse movement dancing back and forth. Once you get the hang of Fusion, I am sure it will be much more adaptable in the CAM side to 'optimise' tool paths etc, that other software looked a bit restrictive. Fantastic job. Cheers, Jon

@learningturningmetal 2 года назад

Thanks Jon. I think the OpenBuilds CAM software must use a wierd method for calculating tool paths. It's a shame I didn't video the namplate generated using Fusion 360, as there is considerablt less traverse movement. It's a big learning curve, but that is half of the fun. All the best. Andrew

@trollforge 2 года назад

Andrew, as a Linux user, the font list looked to me like all the usual ones... I'm guessing that what you are thinking of as "the usual ones" are the Windoze proprietary fonts that cost money to include in a software package...

@learningturningmetal 2 года назад

Ah - thanks for the info - I never thought of that. Cheers Andrew

@oleukeman 2 года назад

Congratulations on successfully taking on this cnc router build when you had no experience with this type of machine. I’m curious why the router jumps back and forth while creating the characters. Possibly to minimize heat buildup? Looking forward to the Jerry Howell V twin build. Thanks for sharing your experience.

@learningturningmetal 2 года назад

Thanks mate! The test was produced using the openbuilds cnc software which seems to have a mind of it's own in relation to toolpaths. The oval nameplate gcode was generated using fusion 360 and it was far more efficient (total runtime around 10mins) - a shame I didn't video that bit for comparison. Yeah - the JH should be fun. I purchased the aluminium for the crankcase several months ago but I'm still not sure how to machine it. I think I need to spend some dedicated thinking time on it. Cheers Andrew

@julias-shed 2 года назад

Can’t argue with the results but that tool path is bonkers, it’s jumping around all over the place. Is that a feature of open Cam? Would make sense to machine each letter in turn surely. Wonder if there’s any optimisation settings you can change?

@learningturningmetal 2 года назад

Yeah - OpenBuilds CAM produced a really strange tool path and there is no obvious way to change it. A shame I didn't video the nameplate being machined. The code for that was generated using Fusion 360 and there was far less lateral movement of the head. Cheers Andrew

@velvetpigcnc 2 года назад

Hi, I removed the stock fan from the spindle as it only spins as fast as the motor, so it has a hard time at low speed to do any cooling. I replaced with a 12 volt fan and a 3d printed shroud. Works well. Cheers

@learningturningmetal 2 года назад

Blimey now that is interesting! Well beyond my electrical capabilities though. Maybe post the stl on thingiverse for others to have a go? At what speed did you encounter heating problems - and how long running? Cheers Andrew

@TheOwlman 2 года назад

An impressive result. Doesn't that package have a means to optimise the GCode? It seems to be retracting and moving long distances to a different section rather a lot, which is going to impact the time it takes to engrave. Later.... Aha, Fusion360.... now did it engrave the name plaque in a more efficient way? You failed to show any video of that one! :~D

@learningturningmetal 2 года назад

Yeah - I think the OpenBuilds CAM software has a mind of it's own when generating toolpaths. I messed up and forgot to video the Fusion 360 generated code. It's was miles more efficient. I just need to spend more time learning the Fusion CAM side of things. All very interesting though. Cheers Andrew

@daveticehurst4191 2 года назад

Hi Andrew, sorry skipped through a lot of this as the Fusion 360 was not up my street. I know absolutely nothing about CNC, but it seemed to me that you wasted a lot of engraving time by it doing whatever at one point, then moving up to the other end to do a bit then back up the other end again. Surely you could get it to complete each letter in turn, just as you would type an email or write a letter. If we had to hand write like that engraved we would go totally mental in keeping track of where to go next. Glad you sorted out the ramp up and ramp down times. Regards from Australia.

@learningturningmetal 2 года назад

Hi Dave I am pleased to say that I am not guilty on this one 😊. The openbuilds cnc software must be working to some strange algorithm to generate such an inefficient toolpath. But then again, it is free. All the best. Andrew

@grahampratley3426 2 года назад

Hello Andrew, Thank you for sharing this journey with us. I love how you give clear descriptions and the results speak for themselves- truly excellent! How did you fix the work piece to the bed for the nameplate? I assume you used some form of sacrificial to save your work bed?

@learningturningmetal 2 года назад

Thanks Graham - I just tend to show it how it is. Definately a journey. I should have taken some oval nameplate footage. The code was generated using Fusion 360 which resulted in far more efficient toolpaths. The brass was only 1mm thick, so for work holding I placed it on a bit of aluminium and used the same clamping method shown earlier. Unfortunately I set the cutting out depth to be 1mm, so it didn't quite get there. You live and learn! All the best. Andrew

@Steviegtr52 2 года назад

Well i have followed the build carefully. I can only say brilliant. You have opened up another door of what you can do in the workshop. I guess having nice nameplates made is not cheap. Now the skies the limit. Just a question. Are the tips HSS or Carbide. Regards . Steve.

@learningturningmetal 2 года назад

Thanks Steve. I initially purchased some HSS engraving bits. I've also just recently purchased some tiny carbide end mills. They look fragile, so I will look to reduce the feed rate etc. It's all a massive learning curve for me at the moment. Good fun though. Cheers Andrew

@richardbradley961 2 года назад

well done and thank you andrew. regards richard. p.s when are you taking on commisions for engraving ?

@learningturningmetal 2 года назад

Thanks Richard. No intension at all. This is definately not a money making machine! It's far cheaper going on-line, typing in text and paying £40 or so. However, there has just been a memorial area built in the village, so I might help local folks out for free. Another great way to learn new stuff! All the best. Andrew

@MadeInGreatBritain 2 года назад

Fantastic! Are you taking work bookings? I’ve got lots of little engraving jobs for you if you’d like!

@andrewwhale1197 2 года назад

Thanks mate! Unfortunately I've got too many other commitments on at the moment. However, I will be making some nameplates FOC for the memorial area in my village. Cheers Andrew

@taranson3057 2 года назад

You can draw ovals with cambam you just have to know the trick. I’m trying to learn confusion 360. Feeds and speed is a huge thing to deal with on a CNC router, too fast and the steppers will stall or miss steps, but I think you’re coming along just fine

@learningturningmetal 2 года назад

Thanks for the info - and encouragement! All the best. Andrew

@nickclarke587 2 года назад

Good morning Andrew. Can you tell me where you sourced the aluminium profile you used for your bed? I want to get rid of the mdf bed I have at thd moment. Thanks...

@learningturningmetal 2 года назад

Hi Nick. I got them on ebay uk from a seller called leomax222. About £20 each for the lengths I went for. Hope that helps. Cheers Andrew
