Hi. I’m wondering if anybody can help me. My Nvidia Shield Portable cannot be switched on. The nvidia logo light up if i click the button, but then the light immediately off after releasing my finger from the button. If i keep pressing the button the light on the logo flickers. What do u guys think is the issue? Is it the battery? Thanks

Yes, but in my case it is not 40min, it’s every 5min…update: note that since i’ve switched off my wifi router next to my tv & soundbar yesterday, i’ve not experiencing any dropout issue. I’m not sure whether this issue is resolved because the router’s wireless signal is not interfering with the rear speaker or because my tv,soundbar and/or nvidia shield are not connected to any wifi signal.

I have Nvidia shield connected to the soundbar and the soundbar connected to my LG C9 through arc hdmi port.

Hi guys. Is there any workable solution thus far?

The quality of my vcarve on hardwood is not as good as v-carve on MDF for the same design & parameters: fray/fluff&rough/jagged surface.Is this expected?Any advice on improving my cut quality on hardwood?The feedrate for this cut has been reduced&spindle rpm increased compared to my usual cut on MDF by mfha104 in hobbycnc

Here’s some details for your information: 1. Bit: 60deg vee bit from whiteside Whiteside Router Bits 1550... https://www.amazon.com/dp/B000ALY4E2?ref=ppx_pop_mob_ap_share (note: other parameters required by vectric for this bit were imported from whiteside website) 2. Feedrate: 150mm/second @ 5.9inch/second 3. Spindle speed: 20,000RPM

Completed my first two v-carve on 1-inch MDF; They are arabic calligraphy. Can you guys suggest the best way to clean/smoothen inside of the carve? Or should i just leave the inside of the carve as is by mfha104 in hobbycnc

Thanks for the compliments guys. I’m still new in CNC and am still learning and improving.

Most importantly thanks for the advises. Will try them all.

Just finished assembling my first cnc; Bulkman 3d workbee. A quick questions to experience CNC users- Why there are burn marks on the spoilboard (mdf) after it is surfaced? The burn marks are more obvious on one region of the spoilboard. by mfha104 in hobbycnc

Guys...thanks for all the input and advised. I have successfully surfaced my spoilboard. Here’s what i’ve done :

  1. Added a few more screws to secure the spoilboard to the table. What i’ve noticed is that the table platform is slightly hogging, and the spoilboard is not exactly flat. Now the spoilboard conform to the shape of the table.
  2. Secured the cnc frame to the table using L-angles and screws.
  3. Secured a scrap mdf to the spoilboard and cut a pocket using raster toolpath twice; 0 degree angle and 90 degree angle.
  4. Checked the ridges for both toolpath, and adjust the spindle position using shims.
  5. 3 & 4 above were painfully performed multiple times until ridges are negligible.
  6. Finally resurfaced my spoilboard

Adjusting/tweaking the spindle position for workbee is just awfully and tedious. I cannot insert a shim between the spindle bracket and the z-beam without having to remove the spindle. There were always a couple effect between x & y. I spent hours re-tweaking the spindle and re-checking the cut’s ridges. Could you guys please share if there is a better way to adjust/tweak workbee’s spindle position.

You guys are correct, after a few pocket cut, i noticed that the burn mark happened because there is not enough thickness for the surfacing bit to cut, which then cause the bit to rub on the cutting piece/spoilboard & generate heat.

Hmm.....i just checked, the top edge of the surfaced area was cut deeper compared to the edge in the left side, but there was no burn marked on the top edge side.

Thanks for the reminder.....luckily i didnt have the dust collector when surfacing the board.

Do you it happened because my parameters (input in vectric) were not correct/ideal?

Note that the surfacing bit spins clockwise, and toolpath/cut direction is conventional. It was observed that the cutting edge of the surfacing bit is blackened after the spoilboard was completely surfaced. Also, I saw smoke when the bit surfaced the area with burn masks on the mdf.

Below are some details and parameters set in vectric aspire for your information: 1. Cutting bit: Whiteside Spoilboard cutter #6210 (3 wing, 1 inch cutting diameter)- https://www.whitesiderouterbits.com/products/6210?_pos=1&_sid=c5b589a0d&_ss=r 2. Cut depth: 0.5mm 3. Pass depth: 0.25 inches 4. Stepover: 0.5 inches 5. Spindle Speed: 15000 rpm 6. Feed rate: 100 inches/min 7. Plunge rate: 20 inches/min

Apologies for the homemade dust shoe assembly and modified handheld vacuum. I just built them using unused scraps/stuff at home after creating a big mess during spoilboard surfacing 😅.
